dialkylaminosilanes a number of new rearrangements was observed. When acted upon by ketene, dialkylaminosilanes, depending on the conditions applied, produce either amides of β-siloxyvinylacetic acid (I) (route “a”, scheme A) or amides of silylated acetic acid (II) (routes “b”, “c”). In both cases an intermediate α-siloxyvinyldialkylamine (III) was isolated which may be rearranged to give amide (II).
在对乙烯酮与单或二烷基氨基硅烷的相互作用的研究中,观察到许多新的重排。当受到烯酮作用时,二烷基氨基硅烷根据所施加的条件,会生成β-甲硅烷氧基乙烯基乙酸(I)的酰胺(路线“ a”,方案A)或甲硅烷基乙酸的酰胺(II)(路线“ b”,“ C”)。在两种情况下,均分离出中间体α-甲硅烷氧基乙烯基二烷基胺(III),可以将其重新排列以得到酰胺(II)。
