e)(2-(2-pyridyl)ethyl)amine, PNN, containing phosphine, imine, and pyridyl donor groups and alkyl-, allyl-, and acylpalladium complexes, methylplatinum complexes, and a zerovalent palladium complex containing PNN have been synthesized and characterized with 1H-, 13C-, 31P-, and 15N-NMR. PNN commonly coordinates in a terdentate fashion, resulting in ionic complexes of the type [(PNN)MII(R)]Y (M = Pd
新型的多功能半不稳定的磷-双(氮)配体N-(2-(二苯基膦基)亚苄基)(2-(2-吡啶基)乙基)胺,PNN,包含膦,亚胺和吡啶基供体基团和烷基-,烯丙基和酰基铝配合物,甲基铂配合物和含PNN的零价钯配合物已经合成,并通过1 H-,13 C-,31 P-和15 N-NMR进行了表征。PNN通常以齿状方式进行配位,从而生成[(PNN)M II(R)] Y类型的离子络合物(M = Pd,Pt,R = CH 3,Y = Cl,CF 3 SO 3; M = Pd ,R = C(O)CH 3,Y = CF 3SO 3 ; M =钯,R =η 1 -CH 2 C(H)CH 2,Y =氯,CF 3 SO 3)。PNN的二齿配位是观察[(PNN)的Pd II(η 3 - (CH 3)2 CC(CH 3)C(CH 3)2)] Cl和令人惊奇地也为中性(PNN)的Pd II(C(O CH 3)(Cl)。分离出了前所未有的零价钯络合物(PNN)Pd
