Catalytic C–C double bond cleavage of α,β-enones with a 1-alkene and H2O was carried out in the presence of a (Ph3P)3RhCl catalyst, 2-amino-3-picoline, cyclohexylamine, benzoic acid, and alkyl group-immobilized silica spheres. Upon completion of the reaction, the corresponding ketones were obtained without needing a further hydrolysis step. In this reaction, alkyl group-immobilized silica spheres act
在(Ph 3 P)3 RhCl催化剂,2-氨基-3-甲基吡啶,环己胺,苯甲酸的存在下,进行α,β-烯酮与1-烯烃和H 2 O的催化CC双键裂解酸和固定有烷基的二氧化硅球。反应完成后,无需进一步水解步骤即可获得相应的酮。在该反应中,固定有烷基的二氧化硅球充当中间酮亚胺水解的贮水剂,并充当有机溶液和H 2 O之间的分相器。
