摘　　要：报道了铑络合物催化１，３－丁二烯与苯酚的调聚合反应。结果表明，催化剂活性差异与铑原子上除三苯基之外的其它配体有关。Ｒｈ（ＰＰｈ３）３Ｐｈ是最好的催化剂，能使苯酚转化率达６６．５％，８－苯氧基－１，６－辛二烯的选择性达８９．４０％。研究了反应条件对调聚合反应的影响，最适宜的温度为１２０℃，反应时间是２４ｈ。The rhodium complexes of triphenyl phosphine can catalyze the telomerization of 1,3 hudadiene with phenol. The difference of their catalytic activity was related to other ligand on rhodium except triphenyl phosphine. Rh(PPh 3) 3 Ph was found the best one and the conversion of phenol 66.5%,selectivity of 8 phenoxy 1.6 Octadiene 89.40%. The influence of react conditions on the telomerization was also studiod and the optimum reacting temperature was 120℃, reacting time was 24 hours.
