Definitions
- the present invention relates to a novel N- (phosphinoalkyl) -N- (thioalkyl) amine derivative, a production method thereof, and a metal complex having the compound as a ligand.
- an organic compound (tridentate ligand) having three coordination groups is a metal having two chelate rings by binding to a metal species in a facial form or a meridional form. It has the feature of forming a complex.
- Hemilabile tridentate ligands having electronically non-equivalent coordination groups can function as monodentate and bidentate ligands during the catalytic cycle in catalytic reactions. It has been known. Therefore, in the tridentate ligand, the structure, physical properties, catalytic activity, and the like of the corresponding metal complex can be arbitrarily adjusted by variously changing the structure and combination of the three coordinating groups. Therefore, tridentate ligands and metal complexes thereof occupy important positions in fields such as organic synthetic chemistry, complex chemistry, and catalytic chemistry, and are still actively researched and developed.
- a tridentate metal complex having an imino group in the molecule as one of the coordination groups exhibits high catalytic activity in, for example, a hydrogenation reaction of a carbonyl compound or a dehydrogenation reaction of alcohols, In these catalytic organic synthesis reactions, it is known that the hydrogen atom on the imino group greatly affects the activity expression.
- Examples of such tridentate ligands are symmetric N, N-bis (2-phosphinoethyl) amine and N, N-bis (2-thioethyl) amine, and their ruthenium complexes are It has been reported that it functions as an excellent catalyst in the hydrogenation reaction of esters (Patent Document 1 and Non-Patent Document 1).
