摘要

Abstract: Primary and secondary tetrahydropyranyl (THP) ethers are efficiently transformed to their carbonyl compounds with AgBrO3 and NaBrO3/AlCl3. Ethylene acetals and ketals are transformed to their carboxylic acids and ketones respectively with AgBrO3/AlCl3 in refluxing acetonitrile. AgBrO3/AlCl3 is also able to transform ethylene acetals to aldehydes in refluxing carbon tetrachloride in high yields. In refluxing acetonitrile, ethylene acetals ...
