PHOSPHONIUM SALTS AND PROCESSES FOR PRODUCTION OF AND USES FOR THE SAME, AND PHOSPHINES DERIVING THE SAME AND PROCESSES FOR PRODUCTION OF THE PHOSPHINES

摘要

Phosphonium salts represented by the general formula (see formula I) wherein R1 and R2 each represents a phenyl group which may be substituted by a lower alkyl group, R3 represents a phenylene group which may be substituted by a lower alkyl group, R7 and R8 each represents a hydrogen atom or a hydrocarbon group having 1 to 12 carbon atoms which may be substituted and R9 represents a hydrogen atom or a hydrocarbon group having 1 to 5 carbon atoms which may be substituted: processes for producing the same and uses for the same; phosphines providing the same, and processes for producing said phosphines.
