An efficient palladium-cocatalyst system for vinylation of unsaturated carboxylic acid has been exploited,among which aliphatic amines(ALA)are firstly used as cocatalysts.
The sythesis of Monuron herbicide by oxidative-reductive carbonylation of dimethyamine and p-ClC6H4NO2 using selenium as catalyst and organic base as cocatalyst was studied.
