The reaction of 1-chloro-4-nitrobenzene (1) with dithiols generated in situ from thiouronium salts (2) under PT conditions, which in turn have been procured by the reaction of appropriate α,ω-dibromoalkanes with thiourea have been investigated.The reactions of (1) with various diols have also been investigated and their reaction mechanism is discussed.
