English abstract:
The known procedure (Hansch, C.; et al., 1956) for the prepn. of benzo[b]thiophenes I (R = H, NH2) by catalytic dehydrogenation of 4,3-Et(HS)C6H3R (R as before) is improved by the use of readily accessible catalysts. These were Cu-Cr on activated charcoal or BASF catalysts V-1283 and H 3-10. The dehydrogenation app. (H.; 1953) is simplified by use of an infusion pump. I (R = H, NH2) were obtained in 73% and 65.2% yield, resp.
