An efficient one-pot synthesis of 1,2-benzenedithiol from benzenethiol

Article abstract of DOI:10.1055/s-1992-26132

1,2-Benzenedithiol (3) can be prepared on a molar scale and isolated in 96% yield by a convenient one-pot procedure starting from benzenethiol. This method utilizes recent discoveries on the formation of dilithium 1,2-benzenedithiolate (2) via directed ortho-lithiation of lithium benzenethiolate.
