(vinylthio)benzene (1) and then an electrophilic quenching followed by a further metalation/electrophilic quenching is a general method to prepare in one pot (alkylthio)benzenesortho, alpha-substituted with equal or different groups. The direct dimetalation of 1 affords the ortho, alpha-dilithiated species 15 besides other by-products. Starting from 15 it is possible to obtain in one step ortho, alpha-substituted
