Complexes [MCl2L2] (M = Pd, Pt; L2 = 2,2‘-bipyridine (bpy) or Me2N(CH2)2NMe2 (tmeda)) react with ketones MeC(O)R (R = Me, Et) in the presence of bases (Ag2O or M‘OH (M‘ = Na, K)) to give the new types of ketonyl palladium(II) and platinum(II) complexes [MCH2C(O)R}ClL2] (M = Pd, L2 = N,N,N‘,N‘-tetramethylethylenediamine = tmeda; M = Pt, L2 = 2,2‘-bipyridine = bpy) and [PtCH2C(O)R}2L2] (R = Me, Et
配合物[MCl 2 L 2 ](M = Pd,Pt; L 2 = 2,2'-联吡啶(bpy)或Me 2 N(CH 2)2 NMe 2(tmeda))与酮MeC(O)R( R = Me,Et)在碱(Ag 2 O或M'OH(M'= Na,K))存在下,得到新型的酮基钯(II)和铂(II)络合物[M CH 2 C(O)R} ClL 2 ](M = Pd,L 2=N,N,N ′,N′-四甲基乙二胺= tmeda; M = Pt,L 2= 2,2′-联吡啶= bpy)和[Pt CH 2 C(O)R} 2L 2 ](R = Me,Et,L 2 = bpy)。在存在bpy的情况下,在[Pt(dba)2 ]上氧化添加氯丙酮也会产生[Pt CH 2 C(O)R} ClL 2 ]。[Pd CH 2 C(O)Me} Cl(tmeda)在TlOTf(OTf = CF 3 SO 3)存在下与PhNHNH 2反应,生成环化金属配合物[Pd
