| Abstract: | New compounds a-diphcnylphosphinoacctophcnone(I), a-diphcnylphosphino-2'-acetophenone liydrobromide(III), and 1-adamantyldiphenylphosphinomethylketone hydrobromidc( V) were synthsizcd by the reaction of trimethylsilyldiphcnylphosphine with corresponding a-chloro or a-bromoketoncs. Ethyl diphenylphosphinoacetate (VI) was prepared by the reaction of chlorodiphenylphosphine with lithium enolate of ethyl acetate. Carbonyl compounds were reduced by lithium aluminium hydride to give corresponding secondary alcohols. Diphcnylphosphino-t-butanol(VII) was .prepared from reaction of ester VI with methylmagncsium bromide. The 13C NMR and 31P NMR spectroscopy of them were also given. |
