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

二氧化碳是一种可再生的无毒的C1来源，可转化为各种有用的化学物质。我发现，一个简单的单体钨酸盐[WO4]2-可以在常压下作为各种二氧化碳转化的高效均相催化剂。钨-氧基部分表现出二氧化碳和底物的双功能活化。本体系的有效性通过高产率和对多种底物的适用性而得到证明，例如胺、2-氨基苯甲腈和丙炔醇。

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.
