A convenient method for the preparation of 1-aryl-1,3-dihydrobenzo[c]thiophenes has been developed using a three-step sequence starting from 2-[aryl(methoxy)methyl]benzyl alcohols. Thus, treatment of the starting materials with thionyl chloride gives the

A simple one-pot reaction between alcohols and 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (Lawesson's reagent, LR) affords the corresponding thiols, accompanied by dehydration products, alkenes.Treatment of acyclic 1,4-diols with LR gives the 1,3-dienes. o-(Dihydroxymethyl)benzene derivatives yield the 1,3-dihydrobenzothiophenes when treated with LR.
