tandem reaction involving an intramolecular oxypalladation of an alkyne and an addition to the carbonyl group to quench the carbon-palladium bond to complete the catalytic cycle was developed. The reaction was catalyzed with the cationic palladium(II) species without the necessity of a redox system. aldehyde - alkyne - cationic palladium(II) complex - 3-hydroxymethylbenzofuran - oxypalladation
开发了一种串联反应,该反应涉及炔烃的分子内氧化钯和加成羰基以淬灭碳-钯键以完成催化循环。该反应用阳离子钯(II)物种催化,无需氧化还原系统。 醛-炔烃-阳离子钯(II)配合物-3-羟甲基苯并呋喃-氧化钯
