A simple and efficient procedure was reported for the synthesis of tetrazole derivatives, the chemo and homoselective oxidation of sulfides to sulfoxides in the presence of two Schiff-base complexes of zirconium oxide and copper anchored on MCM-41 as mesoporous and organometallic catalysts under green conditions. All the products were obtained in excellent yields with high TOF values indicating the high activity of the synthesized catalysts. These catalysts were characterized by XRD, TGA, SEM, EDS, FT-IR, TEM, WDX, BET and AAS techniques and can be recycled for several times without significant loss in catalytic activity. The recovered catalysts were characterized by SEM, FT-IR and AAS analysis which shown an excellent agreement with fresh catalysts.

据报道，在绿色条件下，在固定在MCM-41上的氧化锆和铜的两种席夫碱配合物存在下，四唑衍生物的合成，硫化物的化学和均选择氧化为亚砜的方法简单有效，将其化学转化为亚砜。 。所有产品均以高收率和高TOF值获得，表明合成催化剂具有高活性。这些催化剂通过XRD，TGA，SEM，EDS，FT-IR，TEM，WDX，BET和AAS技术进行了表征，可以循环使用几次而不会显着降低催化活性。回收的催化剂通过SEM，FT-IR和AAS分析进行了表征，与新鲜催化剂具有很好的一致性。
