Rearrangements of tetrahydrofuryl- and tetrahydropyranyl-hydrosilanes to oxasilaalkanes, of acetoxymethyl-hydrosilanes to acetoxysilanes, and halogenomethyl-hydrosilanes to halogenosilanes in the presence of palladium catalyst have been studied. The reaction has been shown to proceed more rapidly in tetrahydrofuran and hexane than in benzene or acetonitrile. The progressive replacement of the methyl
在钯催化剂的存在下,已经研究了四氢呋喃基和四氢吡喃基-氢硅烷到氧杂硅烷基烷烃的重排,乙酰氧基甲基-氢硅烷到乙酰氧基硅烷的重排,以及卤代甲基-氢硅烷到卤代硅烷的重排。已经表明,在四氢呋喃和己烷中,该反应比在苯或乙腈中的反应进行得更快。硅原子上的甲基逐渐被苯基取代,减缓了重排,从五元杂环变为六元杂环也是如此。
