- Kinetic Study on the Hydrolysis of 1-N-Naphthylphthalamic Acid (Naptalam)
-
The hydrolysis rate of 1-N naphthylphthalamic acid (Nap) was measured as a function of pH in the range of 0.9-5 and proceeds via undissociated neighboring carboxyl group participation as was proposed for other phthalamic acid derivatives.One of the main h

- Aza-DielsAlder reaction between N-aryl-1-oxo-1H-isoindolium ions and tert-enamides: Steric effects on reaction outcome
-
The synthesis of 5-substituted 6,6a-dihydroisoindolo[2,1-a]quinolin-11(5H)- ones via [4 + 2] imino-DielsAlder cyclization from N-aryl-3- hydroxyisoindolinones and N-vinyl lactams under Lewis acid-catalysed anhydrous conditions is reported. Reactions of N-(2-substituted-aryl)-3- hydroxyisoindolinones with N-vinylpyrrolidone under identical conditions resulted in the formation of 2-(2-substitued-aryl)-3-(2-(2-oxopyrrolidin-1-yl) vinyl)isoindolin-1-one analogues indicating steric hinderance as the cause of deviation. The probable mechanism of the reaction based on the results from X-ray crystallography and molecular modelling is discussed.

- Ternary Complexes of Some Metal Ions with 2,2'-Bipyridyl or 1,10-Phenanthroline as Primary Ligand and Naptalam as a Secondary Ligand
-
In order to explore complexation as a possible mode of action of some pesticides, the binary and ternary complexes of the type MAL+, where M=Co(II), Ni(II), Cu(II), or Zn(II), A=2,2'-bipyridyl (bpy) or 1,10-phenanthroline (phen) and L=naptalam, have been studied potentiometrically in solution.Protonation constant of naptalam and the stability constants of its binary as well as ternary complexes have been reported at constant ionic strength (0.1 M KNO3) and temperature (25 deg).The values of characterising constant (Δ log K) have been found to be positive, zero or small negative.These values have been used to interpret the extent of M->N-base ?-interactions in these systems.On the basis of formation of considerably stable binary and ternary metal complexes of these pesticides, a new mechanism for their mode of action has been proposed.
