N, N-bis (2-dialkylphosphinoethyl) amine borane complex, method for producing the same, and method for producing ruthenium complex having N, N-bis (2-dialkylphosphinoethyl) amine as ligand

摘要

The present invention relates to an N, N-bis (2-dialkylphosphinoethyl) amine-borane complex which is a kind of ruthenium complex exhibiting excellent catalytic activity in hydrogenation reaction and the like, a process for producing the same, and N, N-bis. An object is to provide an efficient method for producing a ruthenium complex having (2-dialkylphosphinoethyl) amine as a ligand. The amine-borane complex (3) can be efficiently produced by reacting the oxazolidinone compound (1) with the dialkylphosphine-borane compound (2) in the presence of a base. Moreover, the ruthenium complex (5) can be efficiently produced by reacting the amine-borane complex (3) and the ruthenium compound (4) in the presence of amines.
