Significance

Nanolayered cobalt–molybdenum sulfide (Co–Mo–S) catalyzed the alkylation of thiols with alcohols to give the corresponding thioethers in ≤96% yield (eq. 1). Co–Mo–S also catalyzed the reaction of benzyl alcohols with hydrogen sulfide to give symmetrical thioethers (eq. 2).


 

Comment

The authors previously reported the preparation of Co–Mo–S and its applications in the hydrogenation of nitroarenes and quinolines (ACS Catal. 2017, 7, 2698; ACS Catal. 2018, 8, 4545). In the alkylation of benzenethiol with benzyl alcohol, the catalyst was recovered and reused five times with a gradual loss of its catalytic activity.
