(R = H, Me) at a molar ratio of 1: 2 involved mainly cleavage of the N-C(=O) bond with formation of up to 80% of N,N-dimethyltrimethylsilylamine Me3SiNMe2 and the corresponding acyl iodide RCOI. In the reaction with N,N-dimethylformamide, formyl iodide HCOI was detected for the first time by gas chromatography-mass spectrometry. The contribution of Me-N bond cleavage, leading to N-methyl-N-trimethylsilyl
碘代(三甲基)硅烷与N,N-二甲基甲酰胺和N,N-二甲基乙酰胺Me 2 NCOR(R = H,Me)的摩尔比为1:2的反应主要涉及NC(= O)键的裂解形成高达80%的N,N-二甲基三甲基甲硅烷基胺Me 3 SiNMe 2和相应的酰基碘RCOI。在与N,N-二甲基甲酰胺的反应中,通过气相色谱-质谱法首次检测到甲酰碘HCOI。Me-N键断裂的贡献,导致N-甲基-N-三甲基甲硅烷基衍生物Me(Me 3Si)NCOR和碘甲烷要小得多。另一副产物是相应的N-甲基酰亚胺MeN(COR)2,其通过初始酰胺与酰基碘的反应形成。碘代(三甲基)硅烷与DMF和DMA反应的主要中间体是季铵盐[Me 2(Me 3 Si)N + COR] I- ,它通过N-CO和N-Me键的解离而分解。
