摘要

20 I StMe3 I SiMe3 sily1) cyclopropylsilane unit (eg, the analogous carbons in 8 absorb at 6- 5.07,-0.68, 1.76). The isomeric minor product (1 3%) was assigned structure 13 on the-basis of its NMR spectra: which clearly revealed a loss of the integrity of the basic structure of 8. These results are explained by the initial formation of silylene 9, rearrangement via ring expansion to silene 11, followed by rearrangement to silylene 12.
