Oxidations. Aikynes of high nucleophilicity such as ethoxy-(trimethylsilyl)acetylene react with electrophilic O3 to give vicinal dicarbonyl derivatives. In contrast to alkylated or ary-lated acetylenes, neither products of complete C-C cleavage nor peroxidic materials were detected as primary products. Ethoxy-(trimethylsilyl)acetylene reacted with ozone to yield a mixture of ethyl 2-oxo-2-(trimethyl)acetate (13) and ethyl trimethylsUyl oxalate (14) (eq 11). The mechanism of this reaction was also discussed. ...
