Alkylation 

* O, S, N-Alkylation Alkylation of alkoxides, thiolates, amines and phosphites is well known. TL 1984, 

25, 4937; TL 1981, 1997; JFC 1977, 10, 329. 

Cyclopropanation 

CF2Br2 in the presence of Zn, reacts with alkenes to generate 1,1-difluorocyclopropane derivatives. 

JOC 1990, 55, 589 

Fluorination 

CF3Cu is prepared from CBr2F2 and couples with aryl, vinyl and allyl halides to give the 

trifluoromethylated derivative. JACS 1986, 108, 832 

Used as a precursor in the Wittig reaction to introduce =CF2 . Aldehydes and ketones are converted 

to 1,1-difluoroalkenes in the presence of PPh3 . SC 1973, 3, 197 


* Radical addition of halogen to alkene Alkenes (RCH=CH2 ) can be halogenated by CF2Br2 using a 

initiator to give RCHBrCH2CF2Br. Alkynes are also halogenated. CL 1991, 1319 


* Nucleophilic displacement Treatment of carbanions with CF2Br2 gives the bromodifluoromethylated 

compound. The sodium salt of 2-methylbenzoimidazole is N-alkylated with CBr2F2 . Subsequent 

reaction with TBAF give the N-trifluoromethylated heterocycle. JFC 2000, 106, 181. 

Rearrangements 

* Ramberg-B¯cklund This reagent is most commonly used in the Ramberg-B¯cklund reaction - the 

reaction can be carried out at room temperature, the by-products are volatile and over halogenation 

of the sulfone does not occur and there is no carbene addition to the alkene. OR 2003, 62, 357

* Deprotection of dithianes Transacetalation of dithianes to diethyl acetals using 1eq. of DBH in 

ethanol. S 1992, 965 

Fluorination 

* Bromofluorination of alkenes In combination with Hydrogen Fluoride-Pyridine complex or Silicon (IV) 

Fluoride. TL 1991, 32, 69 

* Bromofluorination of alkynes Reaction gives (E)-bromofluoroalkenes. Useful intermediates for Pd 

Coupling. TL 1991, 32, 69 

* Dithiolanes to gem difluoro compounds JOC 1986, 51, 3508 

Halogenation 

* Arene to haloarene Bromination of aromatic rings, even electron deficient ones, occurs in the 

presence of strong acids. BCJ 1994, 67, 1918 

* Arene to haloarene Electrophilic bromination of electron rich aromatics. TL 1997, 38, 4415 

* Arene to haloarene Superior to NBS for the regioselective radical bromination of pyrrole in the 2position. 

OSC 1998, 9, 121 

* Benzylic Halogenation Particularly useful for the formation of acid sensitive benzylic bromides - 

better than NBS for these types of compound. Radical bromination in carbon tetrachloride. JOC 

1987, 52, 4477 

Oxidation

Di-tert-butyl dicarbonate 



* Protection of alcohols Not used for protection of alcohols but used for the protection of phenols- 

Phase transfer (BOC2O, Bu4NHSO4 , NaOH, DCM) or BOC2O, DMAP. Cleavage with 3M HCl in dioxane. 

* Protection of amides The rate of reaction with BOC2O increases as the acidity of the amide NH 

increases. DMAP catalyst is used. JOC 1997, 62, 2070 

* Protection of amines Used extensively for amine protection. Not hydrolysed under basic conditions 

and is inert to many nucleophilic reagents. A common method for its introduction is (BOC) 2O, NaOH, 

water, r.t. Non aqueous conditions: (BOC) 2O, TEA, DCM are also used. Acidic cleavage e.g. HCl in 

MeOH, TFA, TsOH. Imidazoles are also protected under phase transfer conditions or via NaH 

deprotonation. TL 1988, 29, 3411 

* Protection of thiols Protects thiols, both amine and thiol of cysteine is simultaneously protected. 

Treatment with HCl in EtOAc selectively removes the S-Boc group. JOC 1994, 59, 3216

Diethylzinc, 1M solution in hexane 



* Cyclopropanation Reaction of diethylzinc with diiodomethane produces ICH2ZnEt or (ICH2 ) 2Zn insitu 

which are excellent cyclopropanation reagents (Furukawa method). Electron rich alkenes give the 

best results and the presence of air accelerates the reaction and improves the yields. BSJ 1972, 

45, 1946 


* 1,4-Addition The Michael addition of diethylzinc to ,-unsaturated ketones proceeds well in the 

presence of a nickel catalyst. Good enantioselectivities are obtained with chiral ligands. JACS 

1993, 115, 7027 

* Acid chloride to ketone Diethyl zinc reacts with acid chlorides to give the ethyl ketone with Pd(0) 

catalysis. JOC 1984, 49, 2288 

* Hydrometallation Diethyl zinc, in the presence of ZrCp2I2 or ZrCp2Cl2 , adds to terminal alkynes with 

a low degree of regioselectivity, however, addition to internal alkynes proceeds with good 

regioselectivity, leading to tetrasubstituted alkenyl iodides. OM 1983, 2, 563 

* Nucleophilic addition/ carbonyl to alcohol Addition of diethyl zinc to aldehydes and ketones is 

catalysed by aminoalcohols. (-)-3-Exo-(dimethylamino)isoborneol shows a particularly high catalytic 

activity -with 2 mol % of this catalyst, the addition of diethylzinc to benzaldehyde in toluene is 

complete within 6h. at 0°C with 98% ee. JOM 1990, 382, 19

Arylation 

* C-Phenylation Phenylation of carbanions is possible with this reagent, especially with the substrates: 

1,3-dicarbonyl compounds, -cyano ketones, aromatic ketones, acetone enolates and nitronate 

ions. JOC 1964, 29, 2108 

* N-Phenylation Phenylation occurs on hydroxamic acid derivatives, imides, sulfonamides, and certain 

other nitrogen heterocycles. Reaction with aromatic and aliphatic amines requires a CuI catalyst. 

Heteroatom phenylation on N requires Pd(0) or Cu (I) catalysis. SL 2000, 1022 

* O-Phenylation Oxygen anions and nucleophiles are readily phenylated, including alkoxides; 

phenoxides; carboxylates; sulfonates; N-oxides; oximes; hydroxylamines and nitroso compounds. 

JOC 1971, 36, 1780 

* S-Phenylation diaryl or dialkyl sulfides give sulfonium salts Izv. Akad. Nauk SSSR, Ser. Khim. 1973, 

1678; TL 1981, (22), 3629; JOC 1978, 43, 3055 

Electrophilic reagent 

* Reaction with inorganic anions Reacts with inorganic anions e.g. cyanide gives phenyl cyanide, 

sodium azide gives phenyl azide. JOC 1975, 40, 3010 


* Carbonylation palladium catalysed carbonylative cross coupling of diphenyliodonium salts with 

organotin or boron compounds with atmospheric CO at room temperature gives high yields of phenyl 

ketone S 1998, 823 

* Heck the Heck reaction with diphenyliodonium salts occurs under very mild conditions JOC 1996, 

61, 2604 

* Hiyama reaction with organofluorosilanes is catalysed by Pd(0) in the presence of TBAF T 1997, 53, 

3027

3607 

* Sonogashira reaction with terminal alkynes proceeds readily in the absence of base using Pd(OAc)2 

or CuI. CC 1996, 835 

* Stille cross coupling occurs between organostannanes and diphenyliodonium salts SC 1996, 26, 

4311 

* Suzuki Palladium catalysed cross coupling with boronic acids and other organoboranes occurs 

readily under mild conditions, often preferred over the cross coupling with iodobenzene. JOC 1996,
