The salt elimination reactions of [NEt4][Mo(CSe)(CO)2(Tp*)] ([NEt4][2], Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with a range of metal halide complexes (ClMLn) have been investigated as a possible route to isoselenocarbonyl complexes [Mo(CSeMLn)(CO)2(Tp*)]. Thus the reactions of [NEt4][2] with [RuCl(L)2(η-C5R5)] provide molybdenum-ruthenium derivatives [Mo{CSeRu(L)2(η-C5R5)}(CO)2(Tp*)] (L = PPh3, R = H 4, L = CO, R = Me 5), both of which were structurally characterised. The molybdenum-iron derivative [Mo{CSeFe(CO)2(η-C5H5)}(CO)2(Tp*)] (6) was obtained from [NEt4][2] and [FeCl(CO)2(η-C5H5)] however its formulation currently rests on spectroscopic and microanalytical data. The reaction of [NEt4][2] with [RuH(NCMe)(CO)2(PPh3)2]PF6 affords the structurally characterised hydrido-isoselenocarbonyl complex [Mo{CSeRuH(CO)2(PPh3)2}(CO)2(Tp*)] (7) with no indication of coupling of the hydride and selenocarbonyl ligand.
[NEt4][Mo(CSe)(CO)2(Tp*)]（[NEt4][2]，Tp* = 三(3,5-二甲基吡唑-1-基)硼酸酯）与一系列金属卤化物配合物（ClMLn）的盐消除反应已被研究作为合成异硒羰基配合物[Mo(CSeMLn)(CO)2(Tp*)]的可能途径。因此，[NEt4][2]与[RuCl(L)2(η-C5R5)]的反应提供了钼-钌衍生物[Mo{CSeRu(L)2(η-C5R5)}(CO)2(Tp*)]（L = PPh3，R = H 4，L = CO，R = Me 5），两者均进行了结构表征。[Mo{CSeFe(CO)2(η-C5H5)}(CO)2(Tp*)]（6）是由[NEt4][2]和[FeCl(CO)2(η-C5H5)]反应得到的，但目前其结构仅基于光谱和微量分析数据。[NEt4][2]与[RuH(NCMe)(CO)2(PPh3)2]PF6的反应得到了结构确证的氢代异硒羰基配合物[Mo{CSeRuH(CO)2(PPh3)2}(CO)2(Tp*)]（7），其中没有氢化物和硒羰基配体偶联的迹象。
