(1-diazo-2-oxoalkyl) silanes 6a-1 results in Wolff rearrangement yielding silyl ketenes 8a-1. From (1-diazo-3,3-dimethyl-2-oxobutyl) silanes 6c-f, 2-silyl-cyclobutanones 9c-f are formed as by-products, arising from intramolecular C/H insertion of the acyl carbene intermediate. Irradiation of diazo-triisopropylsilyl-acetamide 6m yields only β-lactam 16 and γ-lactam 17. Wolff rearrangement also takes place on copper triflate
(1-重氮-2-氧代烷基)硅烷6a-1的光化学分解导致Wolff重排,产生甲硅烷基烯酮8a-1。由(1-重氮-3,3-二甲基-2-氧丁基)硅烷6c-f形成副产物2-甲硅烷基-环丁酮9c-f,这是由于酰基卡宾中间体的分子内C / H插入而引起的。重氮-三异丙基甲硅烷基乙酰胺6m的辐照仅产生β-内酰胺16和γ-内酰胺17。Wolff重排也发生在三氟甲磺酸铜催化的6a,c,1分解上,而1-oxa-2-sila-4-环戊烯19则由6f获得。,可能是由于卡宾铜中间体的SiC / H插入的结果。
