摘要

Chapman & Hall: New York, 1982. readily prepared by reacting carbonyl compound with trialkyl orthoformates in the presence of Nafion-H in dichloromethane solution. Utilizing this reaction we have also developed a one-pot procedure to convert carbonyl compounds directly to their alkyl ethers. Treatment of the carbonyl compound with trialkyl orthoformate (without isolation of acetals or ketals) followed by addition of triethylsilane and reflux gives ...
