Catalyst‐Free Suzuki‐Type Coupling of Allylic Bromides with Arylboronic Acids
The coupling of arylboronic acids with electron-rich allylic bromides is accomplished in the absence of any transition-metal catalyst through conventional heating. The reaction is completelyExpand

Homogeneous catalytic hydrogenation of free carboxylic acids in the presence of cluster ruthenium carbonyl hydrides
Abstract Saturated monocarboxylic acids up to C 6 , several bicarboxylic acids and some of the corresponding anhydrides are hydrogenated in the homogeneous phase with H 4 Ru 4 (CO) 8 (PBu 3 ) 4 asExpand

Homogeneous catalytic hydrogenation dicarboxylic acid esters. II
Abstract Hydrogenation of dimethyl oxalate in the presence of Ru(CO)2(CH3CO-O)2(PBu3)2 gives methyl glycolate and subsequently ethylene glycol. The formation of the glycol is favoured by hydroxylatedExpand
