* Allylation Various allylic compounds form the Pi-allylpalladium complex with this catalyst. This 

complex reacts with C, O and N nucleophiles. Metal Catalysed Cross Coupling Reactions Suzuki, A; 

Eds Diederich, F; Stang P. J; Wiley VCH, NY, 1998 

* Heck Homogenous catalyst for many organometallic reactions. Light sensitive and unstable in air. 

Aryl halides (I, Br)/ aryltriflate/diazonium salt reacts with alkenes or alkynes (particularly with electron 

withdrawing groups) in the Heck reaction. Electron rich heterocycles e.g. furans, thiophenes, pyrroles 

undergo arylation with aryl halides. Palladium Reagents and Catalysts Wiley, 2004, 2nd Ed., Chapter 

3, sect ion 2; BCJ 1998, 71, 467 

* Hiyama Requires a stoichiometric amount of a promoter typically TBAF or TASF. Catalyst for the 

reaction of aryl and alkenylsilanes, silanols and alkoxysilanes with aryl halides. Metal Catalysed 

Cross Coupling Reactions Suzuki, A; Eds Diederich, F; Stang P. J; Wiley VCH, NY, 1999 

*Negishi Catalyst for the coupling aryl and alkenyl halides with Zn-acetylides (Negishi reaction) and 

with Sn-acetylides (Kosugi-Migita-Stille reaction). Mg acetylides are also used. CRV 2003, 103, 

1979 

*Negishi Catalyst for the reaction of aryl, alkenyl and alkyl zinc reagents with alkenyl and aryl halides 

generally proceeds in high yields and tolerates a wide range of functionality. Metal Catalysed Cross 

Coupling Reactions Suzuki, A; Eds Diederich, F; Stang P. J; Wiley VCH, NY, 2000 

* Sonogashira Catalyst for the coupling of terminal alkynes with aryl halides/aryl triflates in the 

presence of the palladium catalyst and CuI. Often carried out in triethylamine. CRV 2003, 103, 1979 

* Stille Catalyst for the coupling of aryl and alkenyl halides / arenediazonium salts with aryl, alkenyl 

and alkynylstannanes. Metal Catalysed Cross Coupling Reactions Suzuki, A; Eds Diederich, F; Stang 

P. J; Wiley VCH, NY, 2001 

* Suzuki Catalyst of choice for Suzuki couplings. Coupling of organoborane compounds (boronic acids, 

esters and boronate complexes) with aryl, alkenyl and alkynyl halides/ triflates is of great synthetic 

value generally proceeding in high yields and tolerating a wide range of functionality. Often carried 

out in a water/solvent mix e.g. MeCN, DMF, with a carbonate base. Microwave enhanced. Metal

Thallic trifluoroacetate 



* Formation of thallium reagents Thallated intermediates are not isolated, but are transformed to a 

variety of compounds in a subsequent reaction with nucleophiles, the introduction of the nucleophile 

takes place with very high selectivity: the nucleophile occupies the same position as the thallium. 

E.g. the arylthallium compound can be treated with diborane to provide the arylboronic acid. 

Heterocyclic compounds, such as thiophenes, furans, and indoles also undergo thallation reactions 

cleanly. In The Chemistry of the MetalûCarbon Bond; Hartley, F. R., Ed.; Wiley: Chichester, 1987; 4, 

Chapter "5"; CC 1975, 36; TL 1974, 3391; JACS 19 71, 93, 4841; TL 1969, 2423; JHC 1979, 16, 993 

Oxidation 

* Phenol to quinone Substituted 4- t -butylphenols can be converted to quinones in good yields along 

with hydroquinones, 4-aminophenols, and 4-halophenols. Thallated aromatics also undergo 

oxidation with trifluoro peracetic acid to give quinones. Methoxy-substituted phenylpropanoic acids 

can also be oxidised to p-quinones. T 1970, 26, 4031; AG(E). 1970, 9, 74; JCS(P1) 1972, 1629; JOC 

1978, 43 , 3632 

* Thiol to disulfide Used to effect intramolecular disulfide bond formation in cystine-containing 

peptides under very mild conditions and proceeds in high yields. TTFA has also been used for the 

deprotection of sulfur protecting groups in cysteines and subsequently as an oxidant to yield 

cystines. CC 1987, 163; T 1988, 44, 805

Thiophosgene 



* Alcohol to chlorothioformate Chlorothioformates are precursors of thiocarbonates, thiocarbamates, 

and dithiocarbonates. Diols form cyclic thiocarbonates, which can lead to alkenes. JACS 1981, 

103, 932 

* Amide to isothiocyanate iIothiocyanate, nitrile or thione may be produced depending on the 

conditions used. Joos A.; Wirtz, W. Ger. Patent 2á059á872, 1972 (CA 1972, 77, 88á114) 

* Amine to isothiocyanate Primary aliphatic and aromatic amines are converted to isothiocyanates. 

Many functional groups are tolerated e.g. OH, CO2H, SH when distant from the NCS group. JACS 

1916, 38, 1550 


* Heterocyclic synthesis Reactive groups present in the vicinity of the amine function react with the 

thiophosgene - this can create a ring e.g. a cyclic thione. IJC(B) 1981, 20B, 579

Dehydration 

* Amide to nitrile with TsCl in pyridine. JACS 1955, 77, 1701 

* N-Formamidine to isocyanide With TsCl in pyridine. JACS 1954, 76, 3568 

* Urea to carbodiimide Ureas are converted to carbodiimides in triethylamine. OSC 5, 1973, 555 

Halogenation 

* Alcohol to halide The Cl ion can displace the tosyl group in situ, giving the chloride directly. In 

general, allylic and propargylic alcohols form the halides rapidly, primary alcohols are slower and 

secondary alcohols stop at the tosylate stage. TL 1984, 25, 2295 


* Alcohol to tosylate Used for the tosylation of primary and secondary alcohols, often carried out in 

pyridine. The stereochemistry of the -centre is unchanged. Subsequent displacement of the Ts 

group results in inversion. JOC 1986, 51, 2385 

* Carboxylic acid to ester An ester is rapidly formed when an acid and alcohol in pyridine are treated 

with TsCl. Useful for tertiary alcohols. JACS 1955, 77, 6214 

* Epoxidation With 1 eq TsCl and 2 eq NaH, 1,2-diols are converted to epoxides. 1,3-Diols are 

converted to oxetanes. SC 1993, 285; S 1981, 550 


* Protection of amines The sulphonamide is one of the most stable amine protecting groups and is 

cleaved with Na/NH 3 . Sulphonamides of pyrroles, imidazoles, indoles are less stable and can be 

cleaved by basic hydrolysis. H 1992, 34, 1303 


* Beckmann O-Tosylation of oximes leads to amides via Bechmann rearrangement. JCS 1948, 1514

Trichlorosilane 


Oxidation 

* Alkyne to 1,2-diol 1-Aryl-1,2-ethanediols are obtained from arylacetylenes via palladium catalysed 

hydrosilylation. JACS 2002, 8, 1584 

Reduction 

* Imine to amine Enamines are also reduced to the corresponding amines. BCJ 1991, 64, 2128 

* Ketone to alcohol Catalytic reduction occurs at low temperatures. TL 1999, (42), 7507 

* Phosphine oxide to phosphine This occurs in a sealed tube. Sulfenyl, sulfinyl and sulfonyl chlorides 

are reduced to symmetric disulfides. CL 1986, 613 

* Reductive silylation In the presence of a tertiary amine, certain aromatic carbonyls give the 

corresponding benzylic trichlorosilane which can be cleaved by treatment of a base to give toluene. 

Aromatic esters are unaffected, thus selective reduction in the presence of esters is feasible. JOC 

1973, 38, 3660
