The Schiff bases 4,4’-di(2-hydroxybenzyl imino) diphenylmethane (S1), 4,4’-di(2-hydroxy-5-chloro benzyl imino) diphenylmethane (S2) and 4,4’-di(2-hydroxy-5-bromo benzyl imino) diphenylmethane (S3) were synthesized from the condensation reactions of salicyl-aldehyde, 5-chlorosalicylaldehyde and 5- bromosalicylaldehyde, respectively, with 4,4’-diaminodiphenylmethane and reduced with NaBH4in dry MeOH to obtain N/O-donor type ligands 4,4’-di(2-hydroxy benzyl amino) diphenylmethane (L1), 4,4’- di(2-hydroxy-5-chloro benzyl amino) diphenylmethane (L2) and 4,4’-di(2-hydroxy-5-bromo benzyl amino) diphenylmethane (L3). The novel spiro-bino-spiro-cyclotriphosphazene derivatives 1 – 3were obtained from the reactions of L1-L3 with trimer (N3P3Cl6). The identities of these compounds were elucidated by31P-,1H-,13C-NMR, FT-IR spectroscopy and elemental analysis. The solid state structures of compounds 1 and 2 were determined by single crystal X-ray diffraction. Experimental results on the molecular structures of compounds 1 and 2 were supported by computational studies using Density Functional Theory (DFT) methods with Becke-3-Lee–Yang–Parr (B3LYP) functional and 6–31+G(2d,p) basis set. The experimentally determined values of the bond angles and bond lengths in the compounds are in accord with to those predicted theoretically.

Kinetics and reaction mechanism of the metal ion catalysed hydrolysis of some substituted salicylanils

A kinetic study of the hydrolysis of the imines, salicylanil, its methyl and chloro derivatives and N,N′-disalicylidene-p,p′-diamino diphenyl methane has been done in the pH range 2.20-12.65 in the temperature range 25-55°C. The comparative rates of hydrolysis are in the sequence, salicylanil > meta > para > ortho and salicylanil > N,N′-disalicylidene-p,p′-diamina diphenyl methane. The synthesis of N,N′-disalicylidene-p,p′-diamino diphenyl methane and its characterisation by IR, NMR and mass has been reported. Suitable reaction mechanisms have been suggested for the hydrolysis in acidic, neutral and basic media based on pK1 values of the imines, steric hindrance, inductive effect, resonance and mesomeric effects. The catalytic effect of the transition metal ions, NiII CuII and ZnII on the hydrolysis of the imines has been investigated in detail in the temperature range 30-45°C. The hydrolysis is accelerated as per the sequence Ni II > ZBII > CuII which is in accordance with the Irving and William's order of stability constants of metal chelates involving nitrogen anil oxygen donor ligands. The retardation of the rate at lower CuII concentrations has been attributed to the Jahn-Teller distortion of the metal-complex to achieve stability. From the effect of temperature on the rates of hydrolysis of the imines, the thermodynamic activation parameters have been calculated.
