摘要： A "one-pot" process for the palladium catalyzed coupling of a diazonium salt with an olefinic bond, in the aqueous medium in which the diazonium salt is made, by employing a carboxylic acid as a solvent. Arylacrylic acids and their esters, e.g. the cinnamates, can be produced at low catalyst concentration without first isolating the diazonium salt. The process is applied to the synthesis of 2-ethylhexyl p-methoxycinnamate.
