摘要：

The experimental and calculated C-13, O-17, and Si-29 NMR chemical shifts of silylated ketenes and bisketenes show trends consistent with charge redistribution resulting from neutral hyperconjugative donation from the R(3)Si-C bond to the p orbital on the carbonyl carbon, and are supportive of this mechanism for the striking stability of these species.
