Abstract
An object of the present invention is to provide an optically active phosphine-borane compound and a method for producing the same which are useful for the production of an optically active phosphine ligand and allow easy production of any antipode. There is provided a phosphine-borane compound represented by the following general formula (P-1). There is also provided a method for producing the phosphine-borane compound, the method comprising subjecting a hydrogen-phosphine-borane compound represented by the following general formula (P-2) to a coupling reaction with an optically active isocyanate compound represented by the following general formula (3). In the following formulae, R1 and R2 each represent a hydrogen atom, a hydrocarbon group, or a substituted hydrocarbon group and may be selected so that asymmetry may be induced on the phosphorus atom by the presence of these groups, or may be selected so that asymmetry may not be induced; and R3 represents an asymmetric hydrocarbon group or an asymmetric substituted hydrocarbon group.
