Firstly, a new family of manganese PNN-pincer catalysts was developed for the hydrogenation of quinolines at ambient temperature. Secondly, an iron-Tetraphos system was discovered that allows direct N-aryl pyrrole synthesis from nitroarenes in a hydrogenation/Paal-Knorr cascade. Lastly, the effect of phosphine oxide promoters on cobalt carbonyl precatalysts was evaluated, leading to improved protocols for the reductive etherification of aldehydes and the reductive or carbonylative transformation of oxetanes.
