| Although they are rarely invoked as intermediates in catalytic reactions of small amines, late metal amide complexes have been observed both to effect C-N bond formation through their strong nucleophilicity, and to rapidly exchange with free amines through a simple proton transfer mechanism. Our work aims to exploit both these modes of reactivity by using a chelated metal amide group as a template to cleave N-H bonds and thus activate substrate amines as amide nucleophiles. A series of previously reported chelating amido-phosphine ligands with varying electronic and steric properties have been prepared, and progress toward the synthesis and characterization of relevant complexes of these ligands will be presented. Preliminary investigations of the reactivity of these complexes with amines, particularly with respect to N-H activation and C-N bond formation, will also be discussed. |
