title: Triflic acid-mediated phenylation of N-acylaminoalkyl diethylacetals and N-acyl-2-phenyl cyclic amides.
abstract: The reaction of N-acylaminoalkyl diethylacetals with triflic acid in benzene gave N-acylamino-diphenylalkyls. The proposed intermediates are the N-acyl-2-phenyl cyclic amides, which themselves are similarly converted to N-acylamino-diphenylalkyls.
