AB Catalytic cyclopropanation of commercial 1,2- or 1,4-cis-polybutadiene, respectively, with ethyl diazoacetate catalyzedby [TpBr3Cu(NCMe)] (TpBr3¼hydrotris(3,4,5-tribromo-1-pyrazo-lyl)borate) at room temperature afforded high molecular weight(Mn>105mol 1) side-chain or main-chain, respectively, carbox-yethyl cyclopropyl-substituted polymers with variable and con-trolled degrees of functionalization. Complete functionalizationof 1,4-cis-polybutadiene afforded poly[ethylene-alt-(3-ethoxycar-bonyl-cyclopropene)]. Catalytic hydrogenation of residual dou-ble bonds of partially cyclopropanated polybutadienes providedaccess to the corresponding saturated polyolefins. Thermalproperties are reported.
