iodides through a palladium-catalyzed carbonylation followed by an inter- or intramolecular coupling reaction with alcohols to afford the corresponding esters or lactones, respectively. Styrene derivatives were also efficient substrates in an in-situ Mizoroki-Heck-type cross-coupling reaction with aryl iodides, leading to the effective formation of asymmetric stilbenes. The decarbonylation of cinnamaldehyde
一氧化碳(CO)和苯乙烯衍生物都可以通过钯/碳(Pd / C)催化的肉桂醛衍生物的碳-碳(CC)键裂解反应生成,并有效地用于进一步的钯催化的CC键形成以直接和实际的方式进行反应。衍生自简单且负担得起的CO载体(例如肉桂醛或对苯二甲醛)的CO通过钯催化的羰基化反应,然后与醇进行分子间或分子内偶联反应,有效地用于与各种芳族碘的原位CO固定中相应的酯或内酯。苯乙烯衍生物在与芳基碘化物的原位Mizoroki-Heck型交叉偶联反应中也是有效的底物,导致有效形成不对称的芪。
