摘  要:以具有不同取代基的三苯基膦和亚磷酸酯为配体,铁磁性的钴铑双金属为催化剂,考察双环戊二烯氢甲酰化合成三环癸烷不饱和单醛的反应。结果表明,反应存在一定的诱导期,诱导期越短,反应速率越快;配体上的取代基对反应活性和产物选择性具有显著影响,吸电子取代基催化活性较高,诱导期较短,反应速率较快,但选择性较低。亚磷酸酯配体中以亚磷酸三苯酯效果最好,与三苯基膦相比,转化率和选择性均相对较低。在考察的配体中,三苯基膦作为配体,三环癸烷不饱和单醛选择性最高,达97%。The synthesis of monoformyltricyclodecanes through the hydroformylation of dicyclopentadiene was investigated on Co-Rh/Fe3O4 catalyst by using different substituent groups of triphenylphosphine and phosphite as the ligand. The results showed that there was a certain induction time;the shorter the induc- tion time was,the faster the reaction rate was;dicyclopentadiene conversion and the selectivity to mono- formyltricyelodecanes were significantly affected by different substitute groups of the ligand. It was found that faster reaction rate, shorter induction time and lower selectivity were obtained over the electron with- drawing substituents with higher catalytic activity. Triphenyl phosphite exhibited the best performance a- mong the phosphite, but compared with triphenylphosphine, dicyclopentadiene conversion and the selectiv- ity to monoformyltricyclodecanes were lower. tion of dicyclopentadiene on Co-Rh/Fe3O4 97% was achieved. Triphenylphosphine was the best ligand for the hydroformyla- catalyst, and the selectivity to monoformyltricyclodecanes of
