Synthesis and reactivity of alkoxy(trimethylsiloxy)phosphines and their derivatives

Convenient procedures for the synthesis of new alkoxy(trimethylsiloxy) phosphines and their derivatives starting from the available alkyl hypophosphites and N-trimethylsilyl succinimide are proposed. Some properties of these new phosphines such as nucleophilic substitution of the trimethylsiloxy group at trivalent phosphorus, the Arbuzov reaction, and addition of PH and POSi fragments to multiple carbon-carbon bonds are presented.

A Convenient and Facile Synthesis of Dialkylphosphines

A series of simple dialkylphosphines 2 has been prepared by the thermal disproportionation of dialkylphosphine oxides 1 induced by the R2P(O)Cl/R2PCl system, generated in situ from 1 with a catalytic amount of carbon tetrachloride.

One-pot synthesis of ultra-branched mixed tetradentate tripodal phosphines and phosphine chalcogenides

Ultra-branched mixed tetradentate tripodal phosphines and phosphine chalcogenides have been synthesized by the exhaustive regioselective addition of secondary phosphines, phosphine sulfides and phosphine selenides to available tris(4-vinylbenzyl)phosphine oxide under free-radical conditions (UV irradiation or AIBN) in good to excellent yields.
