摘要：

Methoxymethylsilylene, generated thermally from 1,2-dimethyltetramethoxydisilane, was reacted with benzil, some benzil monoimines and 1,4-diazabutadienes to furnish in medium to good yields 1,3-dioxa-, 1,3-oxaza- and 1,3-diaza-2-sila-4-cyclopentenes via formal 1,4-cycloadditions. With unsaturated ketones and 1-azabutadienes, respectively, analogously 1-oxa- and 1-aza-2-sila-4-cyclopentenes are obtained. These are, however, accompanied by the 3-en isomers. The heterocycles are thermally very stable but sensitive to hydrolysis and oxidation. They are characterized by NMR data.
