A novel method for tosyloxylation of anilides using phenyliodine bistrifluoroacetate (PIFA)
摘要:
The direct tosyloxylation of anilides was described in this Letter. In the presence of phenyliodine bis(trifluoroacetate) (PIFA) and BF3 center dot Et2O, the reaction of anilides with TsOH provided para-tosyloxylated products with high regioselectivity under mild conditions.
