Title:
2,3-BISPHOSPHINOPYRAZINE DERIVATIVE, METHOD FOR PRODUCING SAME, TRANSITION METAL COMPLEX, ASYMMETRIC CATALYST, AND METHOD FOR PRODUCING ORGANIC BORON COMPOUND
Document Type and Number:
WIPO Patent Application WO/2019/172150
Kind Code:
A1
Abstract:
Provided is a 2,3-bisphosphinopyrazine derivative represented by general formula (1). (In the formula: R1, R2, R3 and R4 represent an optionally-substituted linear or branched alkyl group having 1–10 carbon atoms, an optionally-substituted cycloalkyl group, an optionally-substituted adamantyl group, or an optionally-substituted fenyl group. R5 represents an optionally-substituted alkyl group having 1–10 carbon atoms, or an optionally-substituted fenyl group, and each R5 may be the same group or a different group. R6 represents a monovalent substituent. n represents an integer from 0-2.)
