preparations and properties of a new series of compounds of the formula trans-[PtCl2(dialkylsulfurdiimine)L] are reported. In the case of the dimethyl-, diethyl-, diisopropyl- and dineopentyl-sulfurdiimine platinumcompounds two isomers are present in solution, but only one isomer was observed for the di-t-butylsulfurdiimine derivative. 1H and 13C NMR data show that the two isomers interconvert intramolecularly
报道了一系列新的式反式-[PtCl 2(二烷基硫代二亚胺)L]化合物的制备和性质。在二甲基,二乙基,二异丙基和二戊基硫磺二亚胺铂化合物的情况下,溶液中存在两种异构体,但对于二叔丁基硫磺二亚胺衍生物仅观察到一种异构体。1 H和13 C NMR数据表明,两种异构体通过两种不同的途径在分子内相互转化。在一种异构体形式中,异常大的低场化学位移表明存在未键合的金属-烷基相互作用。
