Convenient and efficient procedures were developed for preparation of 3,4,5-trimethoxybenzyl sulfides and ethers containing vinyl, allyl, and propargyl groups proceeding from 3,4,5-trimethoxybenzyl alcohol, elemental sulfur, and thiourea in basic and basic-reductive systems (hydrazine hydrate‒KОН‒DMF, NaBH4‒EtOH, KОН‒DMSO).
