A. Naka et al., SILICON-CARBON UNSATURATED-COMPOUNDS .61. REACTIONS OF SILENES PRODUCED THERMALLY FROM ACYLPOLYSILANES WITH (TRIMETHYLSILYL)ACETYLENE, Organometallics, 15(26), 1996, pp. 5759-5761
The cothermolysis of acetyl- and isopropionyltris(trimethylsilyl)silan
es with (trimethylsilyl)acetylene afforded the ring-opened products de
rived from [2 + 2] cycloadducts, while a similar thermolysis of pivalo
yl- and adamantoylpolysilanes produced [2 + 2] cycloadducts and the ri
ng-opened products.
