Me 4 N [Pt{CH 2C(O)Me} Cl 2(η2-C2 H4)](1)与中性配体反应,得到cis-Me 4 N [Pt{CH 2C(O)Me} Cl 2(L)](L = CO(2),η2-PhCHCH 2(3),η2-PhC = CPh(4),η2-H2CCCMe 2(5),PPh3(6),AsPh3(7)),trans-or/and cis-[Pt{CH 2C(O)Me} ClL 2](L = PPh3(8),AsPh3(9),tht(10),XyNC(11),tBuNC(12),py(17)),[Pt{CH2C(O)Me}Cl(η2-C2H4)(L)](L = py(16))或顺式-[Pt{CH 2C(O)Me} ClL 2](L2 =降冰片二烯(nbd,18),1,5-环辛二烯(cod,19),双二苯基膦甲烷(dppm,20),4,4 '-二叔丁基-2,2'-联吡啶(dbbpy,21))或(2)与[Tl(acac)]反应,得到[Pt{CH 2C(O)Me}(O,O-acac)(η2-C2 H4)](22)与中性配体反应得到[Pt{CH 2C(O)Me}(O,O-acac)(L)](L = CO(23),PPh 3(24),XyNC(25))。通过密度泛函理论研究,解释了py与强π受体配体CO和PR 3对1的不同行为。11反式与2当量XyNC反应得到反式-[Pt{C(O)NHXy}Cl(CNXy)2](13)和反式-[Pt{C(NHXy)2}Cl(CNXy)2]Cl(14)的混合物。第一个是通过重结晶和分离。
Me4N[Pt{CH2C(O)Me}Cl2(η2-C2H4)] (1), reacts either (1) with neutral ligands to afford cis-Me4N[Pt{CH2C(O)Me}Cl2(L)] (L = CO (2), η2-PhCHCH2 (3), η2-PhC⋮CPh (4), η2-H2CCCMe2 (5), PPh3 (6), AsPh3 (7)), trans- or/and cis-[Pt{CH2C(O)Me}ClL2] (L = PPh3 (8), AsPh3 (9), tht (10), XyNC (11), tBuNC (12), py (17)), [Pt{CH2C(O)Me}Cl(η2-C2H4)(L)] (L = py (16)), or cis-[Pt{CH2C(O)Me}ClL2] (L2 = norbornadiene (nbd, 18), 1,5-cyclooctadiene (cod, 19), bis(diphenylphosphino)methane (dppm, 20), 4,4‘-di-tert-butyl-2,2‘-bipyridyl (dbbpy, 21)) or (2) with [Tl(acac)] to give [Pt{CH2C(O)Me}(O,O-acac)(η2-C2H4)] (22) which reacts with neutral ligands to give [Pt{CH2C(O)Me}(O,O-acac)(L)] (L = CO (23), PPh3 (24), XyNC (25)). The different behavior of py and stronger π-acceptor ligands, as CO and PR3 toward 1, has been explained through a DFT study. Reaction of 11trans with 2 equiv of XyNC affords a mixture of trans-[Pt{C(O)NHXy}Cl(CNXy)2] (13) and trans-[Pt{C(NHXy)2}Cl(CNXy)2]Cl (14). The first was isolated by recrystallization and...
