Abstract:
A binaphthol monophosphoric acid derivative of the following formula (1), (2), (3) or (4): ##STR8##wherein each of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 which are independent of one another, is hydrogen, a C.sub.2-20 linear or branched alkenyl group, a C.sub.2-20 linear or branched alkynyl group, a phenyl group, a phenyl group having at least one 2- to 6-positions on the phenyl ring substituted by a C.sub.1-10 linear or branched alkyl group at the 1- to 4-carbon atom, a phenyl group having its nucleus substituted at the 1- to 4-carbon atom by a C.sub.2 -C.sub.10 linear or branched alkenyl group, a phenyl group having its nucleus substituted at the 1- to 4-carbon atom by a C.sub.2-10 linear or branched alkynyl group, a naphthyl group or a C.sub.3-8 cycloalkyl group, provided that R.sub.1 to R.sub.4 are not all simultaneously hydrogen, ##STR9##wherein each of R.sub.5, R.sub.6, R.sub.7 and R.sub.8 which are independent of one another, is hydrogen, a C.sub.1-20 linear or branched alkyl group, a C.sub.2-20 linear or branched alkynyl group, a phenyl group, a phenyl group having its nucleus substituted at the 1- to 4-carbon atom by a C.sub.1-10 linear or branched alkyl group, a phenyl group having its nucleus substituted at the 1- to 4-carbon atom by a C.sub.2-10 linear or branched alkenyl group, a phenyl group having its nucleus substituted at the 1- to 4-carbon atom by a C.sub.2-10 linear or branched alkynyl group, a naphthyl group or a C.sub.3-8 cycloalkyl group.
