One-pot synthesis of 2,3-disubstituted benzo[b]thiophene derivatives from 2-mercaptophenyl ketones.

[摘要]：2-Mercaptophenyl ketones reacted with activated alkyl bromides (BrCH2EWG's), such as bromoacetates, bromoacetonitrile, and bromomethyl Ph ketone, in the presence of two molar amts. of sodium hydride in THF at 0 癈 to afford 2,3-disubstituted benzo[b]thiophenes in generally good to excellent yields.
