Acid-catalyzed dehydration of alcohols is a synthetically useful method for preparing alkenes and this chemistry has also been successfully done with the printed catalyst (Table ). A series of alcohols (21a-f) were prepared by the reactions of acetophenones with aryl Grignard reagents. When these 1,1-diarylethanols were passed through the ABS-SO3H printed catalyst, excellent yields of the 1,1-diarylethenes were obtained. These elimination products included halogenated products (23-25), as well as the aryl ether (26) and heterocyclic ( ) products.
