Abstract

Reaction of (MesCCH&PH with (MesCCH2) 2PCH= CH2 in boiling toluene in the presence of potassium tert-butoxide gives the crystalline neopentyl di (tertiary phosphine)(M~~ CCHZ) ZPCH~ CH~ P (CHZCM~~)~. A similar base-catalyzed reaction of CsH5PH2 with (M~~ CCH~)~ PCH= CHZ in boiling tetrahydrofuran gives the liquid tertiary-secondary diphosphine CsHsP (H) CH2CHzP (CHzCMe3) 2. Base-catalyzed reaction of 2 equiv of ( ...
