摘要
The first 2-silaphosphetane was synthetized by reaction of butyllithium with a β-chlorosilylphosphine, followed by intramolecular cyclisation. Physicochemical data show the existence of an equilibrium between the monomeric form (2-silaphosphetane) and the dimeric form (2,6-disila-1,5-diphosphocane). Thermic decomposition under reduced pressure of the 2-dimethylsila-1-phenylphosphetane, through a β-elimination process, leads to the dimethylsilaphenylphosphimine; this new species with a SiP double bond has been characterized by formation of the dimer (Me2SiPPh)2 and by insertion reaction of the 2-silaphosphetane into the SiP bond. © 1979.
