资源简介：
Stable silyl vinylketenes were prepared via the thermal reaction of Fischer carbene complexes with
triisopropylsilyl- or tert-butyldimethylsilyl-substituted alkynes. The ability of these silyl vinylketenes to
participate with carbenoid reagents in [4 + 1] annulation reactions was investigated. The best results
were obtained with diazomethane and substituted diazomethane reagents, which provided cyclopentenone
products in excellent yields and essentially complete stereoselectivity.
