Aminostyrylanthracene compound, synthetic intermediate thereof, and process for production thereof
View Patent ↗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, R 2 represents an unsubstituted aryl group, R 1 represents an aryl group which may have a variety of substituents, and R 3 to R 5 each represent a hydrogen atom, a cyano group, or a hydrocarbon group.]
1. A phosphonic ester or phosphonium salt represented by one of general formulas [VI] or [VII]:
wherein,
R 105 represents a hydrocarbon group;
R 106 and R 107 are identical or different groups wherein at least one of R 106 and R 107 represents a hydrogen atom, a cyano group, a fluoroalkyl group, a nitro group or a halogen atom;
R 108 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.
2. A phosphonic ester or phosphonium salt as defined in claim 1 , wherein R 105 represents a saturated hydrocarbon group having 1 to 4 carbons.
3. A phosphonic ester or phosphonium salt as defined in claim 1 , which is represented by general formula (39) or (40):
4. A phosphonic ester or phosphonium salt as defined in claim 1 , which is represented by general formula (41) or (42):
5. A phosphonic ester or phosphonium salt as defined in claim 1 , which is represented by general formula (43) or (44):
6. 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 (PPh 3 ), thereby giving a phosphonic ester or phosphonium salt represented by general formulas [VI] or [VII]:
General formula [IX]
P(OR 105 ) 3 ;
wherein,
