title: Organophosphine syntheses via activation of the phosphorus-silicon bond of silylphosphines.
abstract: This paper describes the recent advances in the syntheses of organophosphines by forming several types of phosphorus-carbon bonds via activation of the phosphorus-silicon bond of silylphosphines. In this account, the activation methods are classified into three types: nucleophile-induced activations, reactions with Lewis acid-activated electrophiles, and transition metal catalyzed reactions. Nucleophile-induced activations of silylphosphines, especially by a fluoride, generated a reactive phosphide equivalent for selective formation of a P-C bond. Silylphosphines also reacted selectively with Lewis acid-activated electrophiles. The Lewis acid mediated/catalyzed additions and substitutions, to form sp3-carbon-phosphorus bonds including an asymmetric reaction, are described. Several important types of transition metal catalyzed reactions of silylphosphines are also mentioned in this account. Selective formation of a P-C bond is achieved through these activations to produce a variety of functional organophosphines including optically active ones.
