description

2,3-Dihydrobenzo[b]thiophenes (7a-e) were prepared by the Rh2+ catalyzed reaction of 2H-1-benzothiete (1) and diazo compounds (3a-e). α,β-Unsaturated diazo esters (3b,e) and diazo ketones (3d,e) yielded additionally 4,5-dihydro-1-benzothiepins (11b,c) and 5H-4,1-benzoxathiepins (12d,e), respectively.
