Abstract

Abstract : Cross coupling of an imidazolio-phosphide with a N-heterocyclic bromo-borane gave a neutral analogue of a phosphamethine cyanine cation embodying a zwitterionic phosphide in which dative bonding of P-centred lone-pairs focuses on the imidazole unit. Abstract : Reaction of an imidazolio-phosphide with an N-heterocyclic bromo-borane and NaH afforded a neutral analogue of a phosphamethine cyanine cation. DFT studies were used to analyse the dative bonding across P–C/B bonds and the conformational preferences and imply that the observed conformation is imposed by sterics.
