with P-donor ligands, treatment of chloro compounds 1–4 with diazoalkanes Ar1Ar2CN2 afforded polypyridyl carbene complexes [Ru(η5-C5Me5)(CAr1Ar2)(N–N)]BPh4 (5–8) [Ar1 = Ar2 = Ph (a), Ar1 = Ph, Ar2 = p-tolyl (b)]. Comparative DFT studies of the formation of metallacarbenes from aromatic diazoalkanes are reported. Phosphite complex [Ru(η5-C5Me5)(bpy)P(OEt)3}]BPh4 (9) and acetylide derivatives [Ru(η5-C5Me5)(CCAr)(bpy)]
多吡啶配合物将[RuCl(η 5 -C 5我5)(N-N)](1 - 4)[N-N 2,2'-联吡啶(BPY)(1),4,4'-二甲基-2, 2'-联吡啶(4,4'-Me 2 bpy)(2),1,10-菲咯啉(phen)(3)和4,7-二甲基-1,10-菲咯啉(4,7-Me 2 phen) (4)]通过反应来制备将[RuCl 2(η 5 -C 5我5)] 2与Zn粉在多吡啶配体的存在。不同于相关将[RuCl(η 5 -C 5我5)(L1)(L2)] + [L1,L2 = P(OR)3,PPH 3 ]与P-供体配体,治疗氯的化合物的衍生物1 - 4与重氮烷Ar1Ar2CN 2,得到多吡啶卡宾络合物的[Ru(η 5 -C 5我5)(CAr1Ar2)(N-N)] BPH 4(5 - 8)[AR1 = AR2 = Ph(上一个)中,Ar 1 = PH,AR2 = 对-甲苯基(b)]。报道了由芳
