A series of Ru(II)-p-cymene complexes based on ferrocene-hydrazone were investigated for their catalytic activity in acceptorless dehydrogenative coupling (ADC) reactions. The Ru(II)-p-cymene isonicotinic Fc-hyrazone complex showed better performance in the solvent-free synthesis of 1,2-disubstituted benzimidazoles (up to 88%) and quinazolinones (up to 95%). The catalytic experiments demonstrated good to moderate yields, with hydrogen and water as the only by-products.
A series of ferrocene-hydrazone based Ru(II)-p-cymene complexes were investigated for their catalytic activity towards acceptorless dehydrogenative coupling (ADC) reactions. Ru(II)-p-cymene isonicotinic Fc-hyrazone complex performed better in the solvent-free synthesis of 1,2-disubstituted benzimidazoles (up to 88%) and quinazolinones (up to 95%). The catalysis was extended to a wide range of benzylic alcohols. The synthesis of 1,2-disubstituted benzimidazoles was accomplished with electron-donating/-withdrawing o-phenylenediamines as well. A catalytic structure-activity relationship was established by varying the steric and electronic parameters on the substrates. All the catalytic experiments exhibited good to moderate yields, with hydrogen and water as the only by-products. The prepared complexes were well characterized using analytical and spectroscopic techniques. The molecular structures of the ligands and complex were resolved using single crystal X-ray crystallographic studies.
