Abstract
Starting from readily available alpha-arylsulfonyl-alpha-bromoacetophenones 2 a series of 3,5-diaryl-1,2,4-thiadiazoles and 3,5-diaryl-1,2,4-selenadia zoles were prepared in moderate yield. Reaction of compounds 2 with thioure a or selenourea gave 2-amino-5-arylsulfonyl-4-phenylthiazole or selenazole in good yield.
