Abstract

3-Oxo-1-silaprop-1-enes, when generated by photochemical decomposition of α-diazo-α- silyl carbonyl compounds, cyclize to 1-oxa-2-silacyclobut-3-enes provided that the substituent at C-3 is sterically demanding; otherwise, the head-to-tail cyclodimers (1, 5-dioxa- 2, 6-disilacyclo-octa-3, 7-dienes) are obtained.
