Structure-stability correlations for imine formation in aqueous solution

Imine formation between 25 aldehydes and 13 amines in aqueous solution in the pH range 7-11 was studied by 1H NMR spectroscopy. A three-parameter linear equation correlating logarithms of imine formation constants with pKa and HOMO energies of amines and LUMO energies of aldehydes is proposed. In view of the widespread occurrence of imine-forming processes in both chemistry and biology, the data presented are of significance for physical organic chemistry and of particular interest for dynamic combinatorial chemistry.

Novel pyrazolone dye

A novel pyrazolone dye represented by the following formula (I), which can be effectively used as a filter dye, an irradiation inhibiting dye, an antihalation dye or the like in a photographic light-sensitive material: STR1 wherein R1 and R2 each represents --COOR or STR2 R and R' each represents a hydrogen atom, an alkyl group, or an aryl group or may combine with each other to form a 5- or 6-membered ring; Q1 and Q2 each represents an aryl group; X1 and X2 each represents a linkage group; Y1 and Y2 each represents a sulfo group or a carboxyl group; L1, L2 and L3 each represents a methine group; L4 and L5 each represents an alkylene group; m1 and m2 each represents 1 or 2; n represents 0, 1 or 2; p1 and p2 each represents 0 or 1; q1 and q2 each represent 0, 1, 2, 3 or 4; and s1 and s2 each represents 1 or 2.
