Abstract:
The compound represented by the formula: whereinR independently represents hydrogen atom; C1-C11 alkyl; aryl; or substituted aryl, provided that R represents at least one hydrogen atom, and z is 1 when A is oxygen or sulfur or z is 2 when A is nitrogen, R1 represents a C1-C11 alkyl; aryl; substituted aryl wherein the substitution group is selected from C1-C4 alkyl, perfluoroalkyl, nitro, sulfonate or halo group; arylalkyl; siloxyl of the formula â€”OSiZ3 where Z is selected from phenyl or C1-C4 alkyl; or a hydrocarbyl terminated oxyhydrocarbylene group of the formula â€”(BO)zR7 wherein each B independently is selected from a C1-C4 alkylene or an arylene group, O represents oxygen, R7 represents a C1-C11 hydrocarbyl group and z is an integer of 1 to 4; R2 represents hydrogen atom, aryl, substituted aryl, C1-C11 alkyl, halogen atom or R1 and R2, together, provide a hydrocarbylene or substituted hydrocarbylene which forms an aromatic or non-aromatic carbocyclic ring; R3 represents hydrogen; R4 represents hydrogen atom, a C1-C11 alkyl; an aryl; substituted aryl group; or R3 or R4, together, provide a hydrocarbylene or substituted hydrocarbylene forming a non-aromatic carbocyclic ring; R5 represents a C1-C11 alkyl; C5-C8 cycloalkyl; aryl group; a substituted aryl having one or both ortho positions of the aromatic group substituted with a C1-C4 alkyl, the para position (with respect to the Nâ€”R5 bond) substituted with a hydrogen, nitro, trifluoromethyl, halogen, methoxy, C1-C4 alkyl, sulfonate or fused or unfused aryl group; or a hydrocarbyl terminated oxyhydrocarbylene group of the formula â€”(BO)zR7); or R1 and R5 together form an oxyhydrocarbylene chain, â€”(BO)mBâ€”, wherein each B is independently selected from a C1-C4 alkylene group or an arylene group and m is an integer of 1-4; n represents an integer of 0 or 1; X represents a hydrogen atom or an electron withdrawing group selected from the group consisting essentially of NO2, halo, sulfonate (SO3âˆ’), sulfonyl ester (SO2R), carboxyl (COOâˆ’), a perfluoroalkyl, and a carboxylic ester group; and A represents oxygen, nitrogen or sulfur.
