摘要

Abstract Both elemental iodine and diphenyl diselenides, in the presence of [bis (trifluoroacetoxy) iodo] benzene (PIFA), promote the transformation of internal alkynes into the corresponding 1, 2-diketones. The reactions carried out in the presence of iodine unfortunately did not proceed with complete conversion of the starting alkynes. On the other hand, diphenyl diselenide was more efficient and gave satisfactory transformation of the ...
