A series of bulky pyridine-bridged NHC-Ru complexes have been rationally designed and synthesized; these exhibited very high catalytic activity in the hydrogenation of cyclic and linear carbonates under mild reaction conditions. In the presence of catalytic amounts of a weak base, a broad range of substrates with different ring size and steric bulk were well tolerated, providing methanol and the corresponding diols in excellent yields with a catalyst loading as low as 0.5 mol %.
一系列大体积吡啶桥连的NHC-Ru配合物已被合理设计并合成；这些配合物在温和的反应条件下对环状和线性碳酸酯的氢化反应表现出非常高的催化活性。在催化量的弱碱存在下，各种具有不同环大小和空间位阻的底物都能被良好耐受，以低至0.5 mol %的催化剂负载量提供甲醇和相应的二醇，产率优异。
