When appropriate vinyl sulphides, which are activated by two electron-withdrawing groups at the 2-position, react with diazoalkanes they give 4-arylthio-substituted pyrazolines; these undergo accelerated thermal decomposition in which the arylthio-group migrates to the 5-position, with loss of nitrogen, to furnish exclusively the substituted allyl sulphides.
