Activity of Mo-Mo and Mo-P multiple bonds at the phosphinidene complex [Mo<inf>2</inf>Cp<inf>2</inf>{μ-P(2,4,6-C<inf>6</inf>H<inf>2</inf><sup>t</sup>Bu<inf>3</inf>)}(μ-CO)<inf>2</inf>] in reactions with isocyanides and phosphine ligands
2015, Inorganica Chimica ActaCitation Excerpt :Moreover we assume a transoid positioning of the CO ligands with respect to the P atom based on the absence of detectable P–C coupling (hence a large C–Mo–P angle) in the 13C NMR carbonyl resonance of 2b [22]. We finally note that the C–N stretches appear at frequencies a bit lower than expected for linear-terminal ligands [25], particularly in the case of the CNXyl derivative (2026 and 1993 cm−1), and this might denote a significant bending of the C–N–C chain in solution, perhaps due to steric constraints derived from the presence of the bulky R∗ group in the bridging region. In the same line, the isocyanide 13C NMR resonance of 2b (δ 200.2 ppm) appears more deshielded than expected for a linear-terminal isocyanide, also suggesting significant bending in solution.
