group 3 and organolanthanide NO insertion products, namely, (C5Me5)2Ln[μ-ONN(CH2CH═CH2)O]}2 (Ln = Y, La, Sm). The [ONN(allyl)O]− anions adopt an unusual trans geometry and presumably arise from insertion of NO into the Ln−C(allyl) bond followed by coupling of the (allyl-NO) radical anion with a second molecule of NO. Heating a solution of the yttrium product at 110 °C for 20 h affords (C5Me5)2Y[ONN(CH2CH═CH2)O-κ2O
一氧化氮(NO)反应与(C 5我5)2 LN(η 3 -CH 2 CHCH 2)(THF),以形成所述第一晶体学表征组3和有机NO插入产品,即,(C 5我5)2 LN [μ-ONN(CH 2 CH = CH 2)O]} 2(Ln为Y,La,Sm或)。[ONN(烯丙基)O] -阴离子采用不同寻常的反式几何结构,大概是由于NO插入Ln-C(烯丙基)键,然后将(烯丙基-NO)自由基阴离子与第二个NO分子偶联而引起的。在110℃下保持20小时,得到加热
