An inexpensive, easily available, environmentally benign, and efficient catalyst molybdenum(VI) dioxo (acetylacetonate)2 was used for the direct oxo- and thioetherification of alcohol. This method endures selective molybdenum catalyzed dehydrative synthesis of symmetrical ethers from benzylic secondary alcohols as well as unsymmetrical ethers from the reaction of benzylic secondary alcohols with primary alcohol. Furthermore, we have been also successful in the synthesis of Aryl thioether by using alcohol and thiols.

Several examples of nucleophilic substitution reactions of compounds that have good leaving groups have been previously reported, but the direct use of simple alcohols still remains a challenge because of the poor leaving ability of the hydroxy group. Herein, an efficient and highly chemoselective method for the S-benzylation of a wide range of aromatic and aliphatic thiols has been accomplished in the presence of catalytic amounts (0.1–0.2 mol-%) of indium(III) triflate. Our approach is atom efficient (water is the only byproduct) and suitable to obtain the corresponding unsymmetrical thioethers in excellent yields (up to 99 %). The low loading of catalyst that are needed to obtain extraordinarily high chemoselectivities and the generality of the reaction make this approach unique.

A study was carried out on the reaction of substituted phenylcyclopropanes with equimolar amounts of thiophenols in trifluoroacetic acid.Phenylcyclopropanes resistant to the action of trifluoroacetic acid undergo opening of the small ring in the presence
