A green and efficient catalytic approach for the selective synthesis of imines in air at room temperature was achieved with the aid of newly synthesised diruthenium(II) complexes [(η6-p-cymene)2Ru2Cl2(μ-L)] containing substituted 1,2-diacylhydrazine ligands. All the new complexes were fully characterised by analytical and spectroscopic techniques. The solid-state structure of a representative complex was solved by single-crystal X-ray diffraction analysis. The diruthenium(II) complexes also enable the selective aerobic oxidation of alcohols to aldehydes. The catalytic reaction operates in the presence of air as a green and cheap oxidant, and releases water as the only by-product. A plausible mechanism is proposed for the imine formation, which is believed to proceed via an aldehyde intermediate.

We describe herein the efficient visible-light-responsive polyoxometalate-based multielectron photoredox catalysis induced by in situ coordination of alcohols to the lacuna of TBA4H4[γ-SiW10O36] (I, TBA=tetra-n-butylammonium). The coordination of alcohols to the lacuna of I generated a new highest occupied molecular orbital as the electron donor level and enabled the visible-lightresponsive multielectron transfer from alcohols to I, which could be utilized for aerobic alcohol oxidation and onepot synthesis of N-arylimines starting from nitroarenes and primary alcohols.

Condensation of 2-toluidine and 3-toluidine with benzaldebyde and substituted benzaldehydes (1-8) resulted in the formation benzal-2-toluidines (1a-Sa) and benzal-3-toluidines (1b-8b) respectively. The products were identified on the basis of elemental analysis and spectral studies and screened in vitro for their antifungal potential against three phytopathogenic fungi and two nematodes.
