cis-[PtRL2(SnMe3)]. When the latter complex (R = CHCH2) reacts with X2 or MeX further oxidative addition occurs exclusively at the platinum centre. Aromatic isonitriles (R′NC)co-ordinate to the platinum and give insertion products trans-[PtC(CHCH2)= NR′}ClL2] on heating or carbene complexes with NBunH2. The alkynyl trans-[Pt(CCPh)ClL2] also forms 1 :1 adducts with R′NC and carbene complexes therefrom, but no insertion

生物在通过复分解合成相应的单有机
铂(II)物种方面优于
锂或
镁试剂(L = SnMe 3 R +顺式-[PtCl 2 L 2 ] →反式-[PtRClL 2 ] + SnMe 3 Cl叔膦)。SnMe 3 R的反应顺序为R = C
CPh> CF CF 2 > CH CH 2。还发现该顺序用于
氧化添加SnMe 3R至Pt 0给出顺式-[PtRL 2(SnMe 3)]。当后者的络合物(R = CH CH 2)与X 2或MeX反应时,进一步的
氧化加成仅在
铂中心发生。芳香异腈(R'NC)与
铂配位,并在加热或带有NBu n H 2的卡宾配合物中得到插入产物反式-[Pt C(CH CH 2)= NR'} ClL 2 ] 。炔基反式-[Pt(C
