The synthesis, spectroscopic properties and reactions with neutral donor ligands of the novel six different ligand molybdenum(II) complex [MocCl(GeCl3)(CO)(NCMe)(PPh3)(η-MeC2Me)]
摘要:
The seven-coordinate complex [MoCl(GeCl3)(CO)2(NCMe)2(PPh3)] reacts with an excess of but-2-yne in CH2Cl2 at room temperature to give the six different ligand compound [MoCl(GeCl3)(CO)(NCMe)(PPh3)(eta-2-MeC2Me)] (1) in good yield. Solid-state C-13 NMR spectroscopy suggests that the but-2-yne ligand is donating four electrons to the molybdenum in 1. Preliminary studies of the reaction chemistry of 1 with neutral donor ligands are also described.
