摘要：

The distribution of products from the reaction of several chromium(XI) reagents with various alkynes was studied in order to determine the most efficient reagent for α-oxidation. Chromic acid, chromyl acetate, chromyl chloride, fert-butyl chromate, chromium trioxide-pyridine complex, and pyridinium chlorochromate were compared with regard to their ability to oxidize diphenylethyne, 1-phenyl-l-ethyne, 1-phenyl-l-ethyne, 2-decyne, 5-decyne, 4-octyne, and 7-tetradecyne. The chromium trioxide-pyridine complex and pyridinium chlorochromate were found to be the most efficient reagents for preparing conjugated ynones. © 1979, American Chemical Society.
