SYNTHESE DIRECTE DE PHOSPHINES TERTIARIES RACEMIQUES ET DE CHLOROPHOSPHINES DISSYMETRIQUES

Article abstract of DOI:10.1016/0022-328X(84)80288-0

Racemic tertiary phosphines are obtained from dichlorophenylphosphine by a "one pot" synthesis in two steps: (1) condensation of one equivalent of an organocadmium, and (2) substitution of the second chlorine by another organometallic compound.The phosphines liberated from the resulting complexes can be stabilised by direct complexation with cuprous salts.The monochlorophosphines can be isolated in the first stage when their cadmium complexes are submitted to ligand exchange with pyridine.
