Abstract:
RuII-catalyzed intermolecular double [2+2+2] cycloadditions of 1,6-diynes and alkynylthiocyanates have been developed for the synthesis of 2-aryl thiopyridines. Aryl thiocyanates were isolated chemoselectively as a result of initial intermolecular [2+2+2] cycloaddition product. The method offers
operational simplicity and is atom economical in nature
