PROCESS OF PREPARATION OF PHOTO-ACTIVE COMPOUNDS OF SUBSTITUTED BISMETILENO-SUCC-INIC ANIDRIDES, SUBSTITUTED BISMETILENO-SUCCINIMIDS, AND THEIR INTERMEDIARIES

摘要

Photoactive compounds having the general formulae below are provided CHEM in which A represents oxygen or specified imido groups; P1 represents a 3-furyl, a 3-thienyl, a 3-pyrryl, a 3-benzofuryl or a 3-benzothienyl group, said 3-furyl, 3-thienyl and 3-pyrryl groups which is unsubstituted or substituted in the 2-position and/or the 5-position, with specified substituents; P2 represents alkyl having 1 to 20 carbon atoms, cycloalkyl having 3 to 12 carbon atoms, aralkyl having 7 to 9 carbon atoms, aryl having 6 to 14 carbon atoms which may be unsubstituted or substituted with one or more halogen atoms, or alkaryl having 7 to 22 carbon atoms; and @C* and @C* represent a substituted or unsubstituted bridged polycyclic hydrocarbon residue containing from 7 to 20 carbon atoms in a polycyclic system, said residue having a plane of asymmetry which is parallel to the plane which includes the single bonds extending from carbon atom C* and the anhydride or imide ring, any substituents on the bridged polycyclic hydrocarbyl residue being selected from alkyl groups having 1 to 4 carbon atoms, halogen atoms and hydroxy groups.
