Abstract

A convenient method was worked out for the preparation of 2-mercapto-3-benzo[b]-formylthiophene from 3-bromobenzo[b]thiophene. 2-Mercapto-3-benzo[b]formylthiophene and Schiff bases from it react readily with metal salts to give complexes. The magnetic properties of the chelates were studied, and it was found that the dependence of the magnetic susceptibility on the temperature passes through a minimum for (2-mercapto-3-benzo[b]formylthiophenato)Co and {N,N′-bis(2-mercapto-3-benzo[b]thenylidene) ethylenediaminato}cobalt. On the basis of the magnetic susceptibility data it was concluded that the chelates have planar structures.
