While reaction of carbene-stabilized disilicon L:Si═Si:L (L: = C{N(2,6-(i)Pr2C6H3)CH}2) (8) with HCl·NC5H5 results in carbene-stabilized Si2Cl2 (2) and substituted 1H-imidazole (9), combination of the corresponding Fe(CO)4-modified disilicon carbene complex L:Si═Si[Fe(CO)4]:L (6) with pyridine hydrochloride gives a species containing two push-pull-stabilized parent monochlorosilylenes that are bridged by an Fe(CO)3 unit (7). The nature of 7 was further elucidated by spectroscopic, crystallographic, and computational methods. Spectroscopic data suggest that 7 exists as two diastereoisomers.
当卡宾稳定的二硅化合物 L:Si═Si:L(L: = C{N(2,6-(i)Pr2C6H3)CH}2)(8)与 HCl·NC5H5 反应时,生成卡宾稳定的 Si2Cl2(2)和取代的 1H-咪唑(9),相应的 Fe(CO)4 修饰的二硅卡宾配合物 L:Si═Si[Fe(CO)4]:L(6)与盐酸吡啶结合,得到含有两个推拉稳定的双亲氯硅烯的物种,它们由一个 Fe(CO)3 单元桥接(7)。通过光谱、晶体学和计算方法进一步阐明了 7 的性质。光谱数据表明,7 存在两种非对映异构体。
