these polymeric reagents contained either alkyl alcohol or phenol groups on the polymer backbone. The use of these materials as organocatalysts in a range of Morita-Baylis-Hillman reactions indicated that hydroxyl groups could participate in the reactions and accelerate product formation. In the cases examined, phenol groups were more effective than alkyl alcohol groups for catalyzing the reactions
制备了一系列可溶的,非交联的聚苯乙烯负载的三苯基膦和4-二甲基氨基吡啶试剂。这些聚合物试剂中的一些在聚合物主链上包含烷基醇或酚基。这些材料在一系列Morita-Baylis-Hillman反应中用作有机催化剂表明,羟基可参与反应并加速产物形成。在所检查的情况下,酚基比烷基醇基对催化反应更有效。本文是用于有机合成的非天然双功能聚合试剂的合成和使用的首批报道之一,其中两个官能团可以协同参与反应的催化。
