Tertiary phosphanes are produced by reaction of halophosphanes with organo-magnesium compounds in presence of one or more copper compounds. Tertiary phosphanes of formula (IA) and (IB) are produced by reaction in presence of one or more copper compounds of (1) halophosphanes of formula (IIA) or (IIB) with organo-magnesium compounds of formula (IIIA); or of (2) halophosphanes of formula (IIC) with organo-magnesium compounds of formula (IIIB). PRn1Ar(3-n) (IA); R21P-B-PR12 (IB); PXnAr(3-n) (IIA); X2-P-B-PX2 (IIB); R12PX (IIC); (R1)mMg(Y)(2-m) (IIIA); R1 = 1-12C alkyl, Si(R2)3, 1-8Calkylene-Si(R2)3, 1-12C fluoroalkyl, 4-14C aryl or 5-15C aralkyl; R2 = 1-12C alkyl; n = 1, 2 or 3; Ar = optionally substituted aryl; B = 1-12C alkylene, 2-12C alkenylene, 4-20C arylene, 8-40C bisarylene or 10-30C ferrocenylene (each optionally substituted); X and Y = Cl, Br or I; and m = 1 or 2. An Independent claim is also included for the following compounds : di- (tert.-butyl)phenylphosphonium-tetrafluoroborate; di- (tert.-butyl)phenylphosphonium-hexafluorophosphate; di- (tert.-butyl)phenylphosphonium-hydrogenhexafluorozirconate; and di- (tert.-butyl)phenylphosphonium-hydrogenhexafluorotitanate. |
