trimethylgermylation of N,N-dimethylacetamide (1a) or 1-acetylpiperidine (1b) were carried out. The germyl group was introduced stepwise onto the methyl carbon of the acetyl group to give mono- (3), bis- (6), or tris(trimethylgermyl)acetamides (9b), respectively, in high yields, whereas under similar conditions the second silyl group was usually introduced at the carbonyl-oxygen. The Peterson-type reaction of N,N-d
进行碱辅助的N,N-二甲基乙酰胺(1a)或1-乙酰基哌啶(1b)的三甲基甲硅烷基化和三甲基甲硅烷基化。将该杀菌基逐步引入到乙酰基的甲基碳上,分别以高收率分别得到单-(3),双-(6)或三(三甲基锗烷基)乙酰胺(9b),而在相似的条件下,第二个通常在羰基-氧处引入甲硅烷基。N,N-二甲基(三甲基锗烷基)(三甲基甲硅烷基)乙酰胺(5a)与醛的Peterson型反应优先生成N,N-二甲基-2-(三甲基锗烷基)-2-链烯酰胺(13)。
