Formation of a Silylated 1-Silaallene via an Intermediate 1-Chloro-1-silaallene /
Twofold conjugate addition to a 2,6-dimesitylphenyl-substituted dihaloalkynylsilane yields a silylsubstituted 1-silaallene rather than the isomeric silyne. The dehalogenative intramolecular carbometalation eliminationusing t-BuLi proceeds via stepwise dehalogenation involving an intermediate 1-chlor...

| Izvleček: | Twofold conjugate addition to a 2,6-dimesitylphenyl-substituted dihaloalkynylsilane yields a silylsubstituted 1-silaallene rather than the isomeric silyne. The dehalogenative intramolecular carbometalation eliminationusing t-BuLi proceeds via stepwise dehalogenation involving an intermediate 1-chloro-1- silaallene. Our findings are backed by crystal structure analyses, spectroscopic data, and ab initio calculations. The completely dehalogenated 1-silaallene provides a silyl group at the silaallene core it self, which should allow further functionalization. |
