First catalytic dihydroamination of a phosphaalkyne. Crystal and molecular structure of trans-[PdCl2{P(PriNH)2CH 2But}2]

Abstract

Treatment of a dichloromethane solution of Bu^tCP, containing a catalytic amount of TiCl_4, with an excess of the primary amines RNH₂ (R = Prⁱ, Bu^t) quantitatively affords the corresponding bis-dialkylaminophosphine P(Bu^tNH)₂- CH₂Bu^t. P(PrⁱNH)₂CH₂Bu^t is structurally characterised by a single crystal X-ray diffraction study of its bis-trans-PdCl₂ complex.
