摘要：

Photolysis of trimethylsilylcarboalkoxy diazoacetates in alcohols yields the products of insertion of the corresponding carbenes into the O-H bond, compounds derived from Wolff rearrangement, and the compounds most simply attributed to trapping of silenes. However, in the gas phase the immediate precursor to this third type of compound is not the silene but rather a dimethylalkoxysilylketene. The source of this ketene is discussed. Dimethylphenylsilylcarboalkoxycarbene is shown to yield a similar ketene very efficiently. Reactions of trimethylsilylcarbene and of phenyltrimethylsilylcarbene in alcohols are also described. © 1979, American Chemical Society. All rights reserved.
