Abstract
This invention is an aminostyrylanthracene compound represented by, for example, the following general formula [I]. This compound is produced by condensation from a corresponding aminobenzaldehyde and a phosphonic ester or phosphonium salt. [where, in the general formula [I] above, R2 represents an unsubstituted aryl group, R1 represents an aryl group which may have a variety of substituents, and R3 to R5 each represent a hydrogen atom, a cyano group, or a hydrocarbon group.]
Claims10
A phosphonic ester or phosphonium salt represented by one of general formulas [VI] or [VII]:
- wherein,
- R105 represents a hydrocarbon group;
- R106 and R107 are identical or different groups wherein at least one of R106 and R107 represents a hydrogen atom, a cyano group, a fluoroalkyl group, a nitro group or a halogen atom;
- R108 represents a hydrogen atom, a saturated or unsaturated hydrocarbon group having one or more carbons, or any aryl group which may have a substituent;
- and
- X represents a halogen atom.
A process for producing a phosphonic ester or phosphonium salt comprising the steps of:
- reacting a halogenated aryl compound represented by general formula [VIII] with a trialkyl phosphite represented by general formula [IX] or triphenyiphosphine (PPh3), thereby giving a phosphonic ester or phosphonium salt represented by general formulas [VI] or [VII]:
- General formula [IX]
- P(OR105)3;
- wherein,
- R106 and R107 are identical or different groups wherein at least one of R106 and R107 each represents a hydrogen atom, a cyano group, a fluoroalkyl group, a nitro group, or a halogen atom;
- R108 represents a hydrogen atom, a saturated or unsaturated hydrocarbon group having one or more carbons, or any aryl group which may have a substituent;
- X represents a halogen atom;
- and
- R105 represents a hydrocarbon group.
