Synthesis of Ni(Ⅱ)-3,5-dichloro-2-hydroxybenzenesulfonyl chloride supported SBA-15 and its application as a nanoreactor catalyst for the synthesis of diaryl sulfides via reaction of aryl halides with thiourea or S_8

摘要

In the present work, SBA-15 mesoporous grafted with 3-(trimethoxysilyl)-1-propanethiol as a linker and subsequently reacted by 3, 5-dichloro-2-hydroxybenzenesulfonyl chloride. Then to obtain the new catalyst Ni(II) was supported on functionalized SBA-15 by using Ni(NO3)(2) as Ni(II) source. The Ni/SBA-15 catalyst was characterized with SEM, EDS, ICP, XRD, TGA, FT-IR and N-2 sorption-desorption analysis. The key advantages of this heterogeneous catalyst are inexpensive, short reaction times, excellent yields, recovery and reusability.
