摘要

General procedure: The silyl enol ether (2 mmol) and alkyl halide (2.1 mmol) are successively added to a suspension of AgOCOCF 3 (2.1 mmol) in dry CH 2 Cl 2 (2 ml) with stirring under argon at −70 to 25°C (see Table). The reaction is usually complete after 10 min at 25°C. Finally, the mixture is filtered over celite.
