The present invention relates to titanium catalysts for synthesis reactions produced by bringing a reaction mixture comprising a titanium alkoxide and a ligand in contact with water, wherein the ligand is represented by the general formula (e), wherein R1, R2, R3, and R4 are independently a hydrogen atom, an alkyl group, or the like, and (A) represents a group with two or more carbon atoms. The titanium catalysts may be isolated in solid form and may be stored. The invention further relates to a process for cyanation of imines, wherein the process comprises reacting an imine with a cyanating agent in the presence of the titanium catalyst.
本发明涉及用于合成反应的钛催化剂,通过将包含钛烷氧化物和配体的反应混合物与水接触而产生,其中配体由通用公式(e)表示,其中R1、R2、R3和R4分别是氢原子、烷基或类似物,(A)代表具有两个或更多碳原子的基团。这些钛催化剂可以以固体形式分离并储存。该发明还涉及一种亚胺的氰化过程,其中该过程包括在钛催化剂存在下将亚胺与氰化剂反应。
