Diphenylphosphinyl chloride<br />
APPLICATION GUIDE<br />
Coupling Chemistry<br />
* Coupling agent Used for the activation of acids via in situ formation of the diphenylphosphinic mixed<br />
anhydrides. Used in peptide chemistry. These mixed anhydrides react with amines (primary amines<br />
give better yields than secondary amines) to give amides and with thiols to give thiol esters.<br />
Recommended for the preparation of amides from acrylic acids. JCS(P1) 1985, 461; S 1980, 385<br />
Organometallic Chemistry<br />
* Acid to ketone Acids are converted to ketones via activation to the mixed anhydride, followed by<br />
reaction with organometallic reagents such as ethylmagnesium bromide. CC 1986, 412<br />
Protecting Group Chemistry<br />
* Protection of amines Used for the N-protection of amino esters (N-methylmorpholine, DCM). DPP<br />
protecting group is slightly more acid labile than the BOC protecting group. JCS(P1) 1984, 1357<br />

Diphenylphosphoryl azide<br />
APPLICATION GUIDE<br />
Coupling Chemistry<br />
* Peptide synthesis N-Protected amino acids are converted to acyl azides, which undergo Curtius<br />
rearrangement and applied in peptide synthesis. JACS 1972, 94, 6203<br />
Decarbonylation<br />
* Decarbonylation Decarbonylation of primary aldehydes occurs at RT in the presence of catalytic<br />
chlorotris(triphenylphosphine)rhodium(I). Minimal formation of alkene by-product. JOC 1992, 57,<br />
5075<br />
Interconversion of functional groups<br />
* Carboxylic acid to ester An ester is formed in the presence of an alcohol, when no alcohol is added,<br />
the isocyanate is isolated as the product of Curtius rearrangement. CR 1948, 43, 203<br />
Lactonisation, lactamisation<br />
* Macrocyclic lactams Dicarboxylic acids, when activated can condense with diamines to form<br />
lactams. TL 1990, 31, 6469<br />
Oxidation<br />
* Ketone to carboxylic acid Aryl carboxylic acids are obtained from alkyl aryl ketones with the process<br />
proceeding via an enamine intermediate. JOC 1978, 43, 2936<br />
