| Sumario: | [EN] The borrowing hydrogen thioetherification of alcohols overheterogeneous catalysts has emerged as an attractive andpractical synthetic strategy to prepare thioethers from theperspective of green and sustainable chemistry. Developingefficient catalysts is the key to improve this carbon-sulfur (C@S)bond formation process. Herein, a novel catalyst, namely{Mo2.89W0.11S4}n, has been prepared by alloying engineering of itsbasal planes through an innovative synthetic methodology thatmakes use of isostructural building entities based on molybde-num and tungsten sulfide molecular complexes with M3S4(M=Mo, W) cluster cores. Besides excellent activity and reus-ability, {Mo2.89W0.11S4}n is of broad scope, enabling the con-version of structurally diverse thiols and primary as well assecondary alcohols into thioethers. A set of characterizations, incombination with catalytic results, reveal that the catalyticactivity of {Mo2.89W0.11S4}n for this relevant transformation arisesfrom the presence of multiple-type active centers in thedefective basal planes of this alloyed catalyst. More specifically,coordinatively unsaturated sulfurs and metal atoms with Lewisbasic and Lewis acid properties, respectively, are proposed tobe the active sites involved in the borrowing hydrogenmechanism. |
