REACTIONS OF 2-LITHIO-1,3-BENZODITHIOLE WITH CARBON DISULFIDE: FORTH AND BACK PROCESSES

Article abstract of DOI:10.1016/S0040-4039(01)80624-9

Carbophilic reaction of 2-lithio-1,3-benzodithiole with CS2, followed by the addition of a second base equivalent and quenching with MeI, yields 2--1,3-benzodithiole.An unexpected pathway mediated by MeS- and leading to the reformation of the 1,3-benzodithiole anion is described.
