Synthesis of molybdenum arene complexes containing amide-derived heterodifunctional P,O ligands
Abstract
The reactions of the amide-derived ligands Ph2PN(R)C(O)CH3 (R = H, CH3) with the molybdenum arene complexes [Mo(η3-C3H5)(μ-Cl)(η6-C6H5R)]2 (R = H, CH3) have been investigated. A series of complexes in which the functional ligand displays η1-phosphine, η2-acetamidophosphine and η2-phosphinoiminolate coordination have been synthesised and characterised. The crystal structures of the cationic compounds [Mo(η3-C3H5)(η6-C6H6){Ph2PN(R)C(O)CH3-κ2P,O}][PF6] (R = H, CH3) have been determined. The first example of a structurally characterised phosphinoiminolate complex [Mo(η3-C3H5)(η6-C6H6){Ph2PN![[horiz bar, double dot above]](https://www.rsc.org/images/entities/char_e0f2.gif)

is also reported.
