A METHOD FOR PRODUCING VINYLCYCLOALKANES COMPOUNDS

The present invention relates to a method for producing vinylcycloalkanes compounds represented by the general formula (5) highly selectively and economically, which comprises hydrogenation and dehydration. Hydrogenation step: hydrogenating the compounds represented by the general formula (1) or/and (2) or/and (3) or/and (4) with hydrogen to prepare the corresponding primary or secondary alcohols in the presence of hydrogenation catalyst with min. 0.1 part by wight. Dehydration step: dehydrating the corresponding primary or secondary alcohols prepared by the above-mentioned hydrogenation step to prepare vinylcycloalkanes compounds represented by the general formula (5) in the presence of dehydration catalyst. R 1 -CH2-CH2-OH (1) Wherein R 1 of the general formula (1)~(4) is hydrocarbyl (hydrocarbon functional group) having aromatic rings. R 2 -CH=CH2(5) Wherein R 2 of the general formula (5) is cycloalkyl or cycloalkyl-substituted alkyl.

HYDROGENATION OF CARBONYLS WITH TETRADENTATE PNNP LIGAND RUTHENIUM COMPLEXES

The present invention relates to catalytic hydrogenation processes, using Ru complexes with tetradentate ligands of formula L in hydrogenation processes for the reduction of ketone, aldehyde, ester or lactone into the corresponding alcohol or diol respectively. The described processes use a ruthenium complex of the formula (1) as defined below, and where the ligand (L) is defined by the Markush formula shown above.

Visible-Light-Mediated Aerobic Oxidation of Organoboron Compounds Using in Situ Generated Hydrogen Peroxide

A simple and general visible-light-mediated oxidation of organoboron compounds has been developed with rose bengal as the photocatalyst, substoichiometric Et3N as the electron donor, as well as air as the oxidant. This mild and metal-free protocol shows a broad substrate scope and provides a wide range of aliphatic alcohols and phenols in moderate to excellent yields. Notably, the robustness of this method is demonstrated on the stereospecific aerobic oxidation of organoboron compounds.
