Sažetak
Metal-mediated N−H bond activation is the first step of catalytic ammonia transformation into amines. Preparation of metal complexes with ammonia and N−H bond activation are usually performed in solution. Controllable and reversible solid-state conversion of the ammine complex into the amido species, relevant in catalysis, has never been described. Here we report a reversible solvent-free activation of ammonia N−H bond conducted at room temperature in a reaction of gaseous ammonia and solid dicyclopalladated azobenzene complex (Figure 1). In situ Raman monitoring of the gas-solid reaction and UV-vis kinetics in solution show that the reaction is stepwise proceeding via diammine intermediate complex.
