anhydride additives, the catalytic decarbonylation of p-nitrophenylesters of aliphatic carboxylic acids to their corresponding olefins, including commodity monomers like styrene and acrylates, has been developed. The reaction is catalyzed by palladium complexes in the absence of added ligands and is promoted by alkali/alkaline-earth metal halides. Combination of catalytic decarbonylation and Heck-type coupling
为了避免需要酸酐添加剂,已经开发了将脂肪族羧酸的对硝基苯基酯催化脱羰成它们相应的烯烃,包括商品单体如苯乙烯和丙烯酸酯的方法。在不存在添加的配体的情况下,该反应由钯配合物催化,并且由碱/碱土金属卤化物促进。在单锅法中催化脱羰基和Heck型偶联与芳基酯的结合证明了在合成方法中使用羧酸作为“掩蔽烯烃”的可行性。
