Abstract

Cationic rhodium(I) norbornadiene complexes with polystyrene-immobilized imidazole, tetramethylbiimidazole or phosphine ligands in the presence of potassium hydroxide catalyze hydrogen transfer from isopropanol to acetophenone and 1-hexene. [Rh(NBD) (poly-PPh2)2] ClO4 complexes are particularly efficient for the reduction of acetophenone, but slow decomposition to rhodium metal is observed.

Abstract

Катионовые родиевые(I) комплексы норборнадиена с лигандом имидазола, тетраметилбиимидазола или фосфина, иммобилзированных полистиролом, в присутствии гидроокиси калия катализуют передачу водорода с изопропанола на ацетофенон и 1-гексен. Комплексы [Rh(NBD) (поли-PPh2)2]ClO4 особенно эффективны в восстановлении ацетофенона, но наблюдается медленное разложение до металлического родия.
