carboxamides, and carbinol esters) were investigated as substrates for ring-opening metathesis polymerization (ROMP) with [(H(2)IMes)(3-Br-pyridine)(2)(Cl)(2)Ru=CHPh]. Both the secondary amides of 1-cyclobutenecarboxylic acid and the esters of 1-cyclobutene-1-methanol undergo polymerization. The secondary amides provide translationally invariant polymers (E-olefins). Although the carbinol esters yield stereo-
研究了一系列 1-取代的环丁烯衍生物(羧酸酯、羧酰胺和甲醇酯)的反应性,作为开环复分解聚合 (ROMP) 与 [(H(2)IMes)(3-Br-吡啶) (2)(Cl)(2)Ru=CHPh]。1-环丁烯羧酸的仲酰胺和1-环丁烯-1-甲醇的酯都进行聚合。仲酰胺提供平移不变的聚合物(E-烯烃)。虽然甲醇酯产生立体和区域化学异质聚合物,但 1-环丁烯羧酸酯和叔酰胺进行开环复分解 (ROM) 但不进行 ROMP。在 B3LYP/6-31G* 和 LANL2DZ 理论水平上分析了这些 ROMP 和 ROM 反应的区域和立体化学结果。
