Synthesis and structural characterization of facile ruthenium(II) hydrazone complexes: Efficient catalysts in α-alkylation of ketones with primary alcohols via hydrogen auto transfer
successfully applied as catalysts in α -alkylation of aliphatic and aromatic ketones with alcohols via borrowing hydrogen strategy. Various parameters such as base, solvent, temperature, time and catalyst loading on the catalytic activity were analyzed. From the results, the catalyst1 was found to be the best catalyst for α-alkylation reaction to obtain excellent yield. The catalytic system has a broad
3,4-Dihydrocoumarin derivatives were synthesized in a highly enantioselective manner from 3-(2-hydroxyphenyl)cyclobutanones through enantioselective carbon-carbon bond cleavage. A cascade reaction with electron-deficient alkenes introduced a carbon-carbon bond at the 5-position of the dihydrocoumarins.
