Oxidation reactions, coordination chemistry and antibacterial activities with ligand 2-{(diphenylphosphino)methyl}-N,N-dimethylaniline

N,N-dimethyl-o-toluidine was treated with n-butyllithium-tmeda in diethylether/hexane solution to give (2-(dimethylamino)benzyl)lithium which reacts with chlorodiphenylphosphine to form the corresponding hemilabile N,P-ligand 2-PPh2CH2-1-NMe2C6H4 (1). Oxidation of 1 with elemental sulfur or gray selenium gave the corresponding sulfide and selenide 2-(E)PPh2CH2-1-NMe2C6H4 (E = S (2), Se (3)), respectively. The reaction of 1 with M(CO)6 (M = Mo,...
