Abstract
The salt elimination reactions of [NEt 4 ][Mo(CSe)(CO) 2 (Tp∗)] ([NEt 4 ][2], Tp∗ = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with a range of metal halide complexes (ClML n ) have been investigated as a possible route to isoselenocarbonyl complexes [Mo(CSeML n )(CO) 2 (Tp∗)]. Thus the reactions of [NEt 4 ][2] with [RuCl(L) 2 (η-C 5 R 5 )] provide molybdenum-ruthenium derivatives [Mo{CSeRu(L) 2 (η-C 5 R 5 )}(CO) 2 (Tp∗)] (L = PPh 3 , R = H 4, L = CO, R = Me 5), both of which were structurally characterised. The molybdenum-iron derivative [Mo{CSeFe(CO) 2 (η-C 5 H 5 )}(CO) 2 (Tp∗)] (6) was obtained from [NEt 4 ][2] and [FeCl(CO) 2 (η-C 5 H 5 )] however its formulation currently rests on spectroscopic and microanalytical data. The reaction of [NEt 4 ][2] with [RuH(NCMe)(CO) 2 (PPh 3 ) 2 ]PF 6 affords the structurally characterised hydrido-isoselenocarbonyl complex [Mo{CSeRuH(CO) 2 (PPh 3 ) 2 }(CO) 2 (Tp∗)] (7) with no indication of coupling of the hydride and selenocarbonyl ligand.
