Development of bifunctional monomeric metalate catalysts for chemical fixation of carbon dioxide

二氧化碳是一种可再生和无毒的C1源，可以转化为各种有用的化学品。我已经发现，一个简单的单体钨酸盐[WO 4]2-可以作为一个高效的均相催化剂，在大气压下的各种二氧化碳转化。钨-氧代部分显示二氧化碳和底物的双功能活化。本系统的有效性通过高产率和对广泛的底物如胺、2-氨基苯甲腈和炔丙醇的适用性来证明。

Carbon dioxide is a renewable and nontoxic C1 source into various useful chemicals. I have found that a simple monomeric tungstate [WO4]2- can act as a highly efficient homogeneous catalyst for various kinds of carbon dioxide transformations at atmospheric pressure. The tungsten-oxo moiety shows bifunctional activation of both carbon dioxide and substrates. The effectiveness of the present system is evidenced by high yields and applicability to a wide range of substrates such as amines, 2-aminobenzonitriles, and propargylic alcohols.
