We report here the synthesis of new C,N‐chelated chlorostannylenes and germylenes L3MCl (M=Sn(1), Ge (2)) and L4MCl (M=Sn(3), Ge (4)) containing sterically demanding C,N‐chelating ligands L3, 4 (L3=[2,4‐di‐tBu‐6‐(Et2NCH2)C6H2]−; L4=[2,4‐di‐tBu‐6‐(C6H3‐2′,6′‐iPr2)N=CH}C6H2]−). Reductions of 1–4 yielded three‐coordinate C,N‐chelated distannynes and digermynes [L3, 4M]2 for the first time (5: L3, M=Sn
我们在这里报告新的C,N螯合的氯亚锡和亚甲基L 3 MCl(M = Sn(1),Ge(2))和L 4 MCl(M = Sn(3),Ge(4))的合成苛刻的C,N螯合配体L 3,图4(L 3 = [2,4-二-吨卜-6-(ET 2 NCH 2)C 6 H ^ 2 ] - ;大号4 = [2,4-二-吨卜-6 - (C 6 H ^ 3 -2',6'-我镨2)N = CH}℃ 6 ħ 2] -)。的削减1 - 4产生三坐标C,N-螯合distannynes和digermynes [L 3,4中号] 2首次(5:L 3,M = Sn的,6:L 3,M =葛,7: L 4,M = Sn,8:L 4,M = Ge)。为了进行比较,四坐标distannyne [L 5的Sn] 2(10)由N,C,N -螯合物大号稳定5(L 5 = [2,6 - (C 6 H ^ 3 -2',6'-我2)N = CH}
