Abstract

Vinyl groups in phenyl-terminated polybutadienes 1-3, 99% unsaturated, were functionalized with 2-isopropenylpyridine (IPP, 1 equiv.) in the presenceof RhCl(PPh3)(3) (10 mol%). The resulted polymers had about 50% of conversion ratio of 1,2-units of the original polymers. Also, PTPBs 4-5, 60% unsaturated, gave about 45% of conversion ratio in vinyl groups under the same reaction conditions. By using the substrate with several gave 45, 28, 15 and6% of conversion ratios in the vinyl groups, respectively. (C) 2000 Published by Elsevier Science Ltd. All rights reserved.
