the corresponding complexes cAAC·SnBr2, 3b, cAAC·SnCpCl, 3c, and cAAC·SnCpBr, 3d, which were studied in solution and in the solid state. Although isolatable as crystalline solids, 3c,d exist in a heteroleptic/homoleptic equilibrium with other tin(II) species, in solution. In addition, the coordination chemistry of 3b was investigated and the corresponding iron tetracarbonyl complex, 5, could be isolated
锡(II)二溴化物,2B,和cyclopentadienyltin(II)氯化物,2C,和cyclopentadienyltin(II),溴化2D,用与化合物[环状(烷基)(氨基)卡宾(CAAC),1,得到相应的络合物CAAC· SNBR 2,图3b,CAAC·SnCpCl,3C,和CAAC·SnCpBr,3D,其进行了研究在溶液中和在固体状态。尽管可分离为结晶固体,但溶液中的3c,d与其他锡(II)物种处于杂配/同质平衡状态。此外,还研究了3b的配位化学以及相应的四羰基铁配合物,5,可以被分离并在结构上表征。此外,在DFT框架内通过量子化学计算研究了溶液中3c,d观察到的平衡反应机理,以及所有cAAC配合物的化学键合性质。
