manganese (iii)-bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (mn-bsmp) as an inexpensive n2o2 type schiff base catalyst for oxidative decarboxylation of carboxylic acids with (n-bu4nio4) in the presence of imidazol

in this study, bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (bsmp) as a schiff base ligand of n2o2-type and its mn and fe complex as m-bsmp catalyst were synthesized and characterized by uv-vis, ir spectroscopy and elemental analysis. the efficiency of fe- and mn-bsmp catalysts was evaluated in the oxidative decarboxylation of arylacetic acids with tetra-butylammonium periodate (n-bu4nio4) in the presence of imidazol with the mole ratios of m-bsmp: imdazole: n-bu4nio4: carboxylic acid of 1:2:5:5, respectively in ch2cl2. using mn-bsmp instead of fe-bsmp makes the decarboxylation improved, leading 60-95% of corresponding carbonyl compounds as the sole products.
