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.
Direct coupling reaction between alcohols and allyltrimethylsilane catalyzed by phosphomolybdic acid

Phosphomolybdic acid (PMA) is a simple and efficient catalyst for direct coupling reaction of alcohols with allyltrimethylsilane. Direct nucleophilic allylation of alcohol with allyltrimethylsilane proceeds in considerably good yield in the presence of catalytic amount of (0.5 mol %) PMA at room temperature. Copyright
Unusual case of catalysis by palladium clusters

An unusual for Pd catalysts dehydration of α-alkyl and α, α′-dialkylbenzyl alcohols PhCR′R″OH (R′ = H, Me, Et, Bu; R″ = H, Me) occurs in the presence of the palladium(I) cluster [Pd4(CO)4(OAc)4] (1) in an inert atmosphere to form ethers PhCR′R″-O-CR′ R″ and water. The catalyst is an intermediate of cluster 1 reduction to Pd black, while neither the starting cluster 1, nor Pd black, which is the decomposition product, are active in the catalysis of this reaction.
