| Abstract
| - New cationic molybdenum alkylidene compounds possessing β-diketonate and β-diketiminate ligands have been developed and reactions with olefins examined.
- Reaction of Mo(NAr)(CHCMe2Ph)(OTf)2(DME) (Ar= 2,6-i-Pr2C6H3) with the lithium salt of various β-diketonatesand β-diketiminates leads to complexes of the type Mo(NAr)(CHCMe2Ph)(L)(OTf) (L = β-diketonate or β-diketiminate).Treatment of these compounds with NaB[3,5-(CF3)2C6H3]4 indichloromethane affords rare examples of cationic imidoalkylidene complexes. The solid-state structures of two of thesecompounds, {Mo(NAr)(CHCMe2Ph)(TMHD)(THF)}{B[3,5-(CF3)2C6H3]4} and {Mo(NAr)(CHCMe2Ph)(ArCl-Nacnac)}{B[3,5-(CF3)2C6H3]4} (TMHD = tetramethylheptanedionato,ArCl-Nacnac = [2,6-Cl2C6H3NC(Me)]2CH), have been determined by X-ray diffraction, and their reactivity with ethyleneand other simple olefins has been explored.
