Templated Synthesis and Intact Coordination of a Diorganotriselenane: [RuCl2(PPh3){κ3-Se,N,N‘-Se(mtSe)2}] (mtSe = selenomethimazolyl)
摘要:
The reaction of [ RuCl2(PPh3)(3)] with methimazole (Hmt) under basic conditions provides the simple bis(chelate) complex [Ru(kappa(2)-S, N-mt)(2)(PPh3)(2)], while the selenium analogue Hmt(Se) provides an intact coordinated diorganotriselenane [ Ru{ kappa(3)-Se, N, N'-Se(mt(Se))(2)}Cl-2(PPh3)]. Bidentate mt(Se) coordination is however observed in the complexes [RuR(kappa(2)-Se, N)(CO)-(PPh3) (2)] ( R=H, CH=CHC6H4Me- 4).
