New molybdenum(0), molybdenum(II), manganese(I), rhenium(I), silver(I), and copper(I) complexes with the 1,3,5-tris(thiocyanatomethyl)mesitylene [Ms(CH2SCN)3] ligand have been synthesized and characterized by IR, NMR, and by X-ray diffraction (except for the rhenium complex). The Ms(CH2SCN)3 ligand coordinated with the molybdenum, manganese, and rhenium carbonyl fragments as a tripodal chelate. With
新的钼(0),钼(II),锰(I),rh(I),银(I)和铜(I)与1,3,5-三(硫氰酸根合甲基)亚甲基[Ms(CH 2 SCN)3 ]配体已经合成,并通过IR,NMR和X射线衍射进行了表征(except络合物除外)。Ms(CH 2 SCN)3配体与钼,锰和rh羰基片段配位,形成三脚架螯合物。用铜和银,获得了二聚的双键型物质,同时Ms(CH 2 SCN)3配体同时充当双齿螯合物和桥键。的[的Cu(MS(CH 2 SCN)3)} 2 ] [巴' 4] 2(巴' 4 =四(3,5-双(三氟甲基)苯基)硼酸盐)产物是由carbene-和氮烯转移反应的装置,用于环丙烷化和烯烃和炔烃的cyclopropenation的氮杂环丙烷的良好催化剂。
