首次报道了一种由（2，2 ′-bipy）RuCl_3（CH_3OH）和十六烷基三甲基氯化铵组成的高效催化剂，用于在温和条件下（75 ℃，3.0 Wa）由二氧化碳和环氧丙烷形成碳酸丙烯酯。碳酸丙烯酯的选择性和收率接近100%。该催化剂易于回收，重复使用5次，总转化数达2.04 × 10 ~（4），转化频率大于1000 h ~（-1）。提出了反应机理。(c)2007年由Elsevier B. V.出版。
A highly efficient catalyst composed of (2,2'-bipy)RuCl3(CH3OH) and cetyltrimethylammonium chloride is reported for the first time for the formation of propylene carbonate from carbon dioxide and propylene oxide under mild conditions (75 degrees C, 3.0 Wa). Nearly 100% selectivity and 100% yield of propylene carbonate was achieved. The catalyst can be easily recovered and reused several times without appreciable loss of catalytic activity, total turn over number reaching 2.04 x 10(4) after five catalytic recycles with a turnover frequency higher than 1000 h(-1). A mechanism for the reaction was proposed. (c) 2007 Published by Elsevier B.V.
