Abstract

An efficient one-pot, three-component synthesis of novel push-pull 1,3-benzodithiol-2-ylidenes, involv-ing reaction of active methylene compounds with CS2 in the presence of NaH as the base, followed by in situ Cu-catalyzed bis-C-S coupling of the resulting dithioate salts with 1-bromo-2-iodobenzenes has been reported. The methodology involves readily available starting materials and tolerates a broad range of functional groups. (C) 2022 Elsevier Ltd. All rights reserved.
