Application of Ni-based metal-organic framework as heterogeneous catalyst for disulfide addition to acetylene

Several recent studies have shown unique adsorption activity of metal organic frameworks (MOFs) towards unsaturated hydrocarbons. In the current article, we explored the application of Ni-MOFs for S-functionalization of acetylene. We showed that Ni-MOF-74 catalyzed the reaction of disulfide addition...

Description
Summary:Several recent studies have shown unique adsorption activity of metal organic frameworks (MOFs) towards unsaturated hydrocarbons. In the current article, we explored the application of Ni-MOFs for S-functionalization of acetylene. We showed that Ni-MOF-74 catalyzed the reaction of disulfide addition to gaseous acetylene with excellent selectivity. The prime advantage of the proposed Ni-MOF-74 over other examined catalysts was its easy separation and recycling possibility. Moreover, it demonstrated no leaching of Ni species into the solution. The work was supplemented with a study on the catalyst behavior in the course of the reaction by using SEM, EDX, XRD, and FT-IR methods. [Display omitted] •The first example of Ni-MOF-74 catalyzed S-functionalization of acetylene is reported.•The Ni-MOF-74 is stable to leaching of Ni species to solution.•It was found that the method of Ni-MOF-74 synthesis effects MOF catalytic activity.•Experimental study of MOF structure modification during catalytic process is provided.
