- TRIPHENYLPHOSPHINE DERIVATIVES
-
The present invention relates to a triphenylphosphine of Formula (I) wherein M is a proton or a monovalent or divalent cation, n is an integer selected from 1 and 2, p takes a value selected from 1/2, 1 and 2, R1 is selected from H, C1-C18 alkyl, CF3 and SO3-, R11, R12 and R13 are independently selected from H and C1-C18 alkyl, with the proviso that if R1 is SO3-, then the product of n and p is equal to 2, R2, R3 and R5 are independently selected from H and C1-C18 alkyl, R4 is H, R6-R10 are independently selected from H, C1-C18 alkyl and CF3, at least one of R6-R10 being CF3; if R1 is not SO3-, then the product of n and p is equal to 1, R1-R10 are independently selected from H, C1-C18 is alkyl and CF3, at least one of the groups R1 -R10 being CF3; the present invention also is directed to a process for obtaining a triphenyl phosphine of Formula (I) and its use as ligand in the catalysis field and other several applications.
