Stereoselective synthesis of pyrazolidinones via dipolar cycloaddition of azomethine imines with active esters under Lewis base catalysis is presented. The active esters are readily generated in situ from the corresponding acids. Products, which are obtai

A series of mixed anhydrides has been prepared and characterized.The reduction potentials and the electronic absorption spectra show an interesting systematic variation which is dependent on the steric requirements of the substituents.X-ray structural results are consistent with theoretical calculations that predict structural variations which are also dependent on the size of the substituent at the anhydride terminus.Taken together, these data show that the relative molecular orbital energies, as influenced by the relative dihedral angle of the two anhydride carbonyl groups, are responsible for the observed changes in physical properties.
AUTOXIDATION OF DIBENZYL KETONE.

Oxidation of dibenzyl ketone in o-dichlorobenzene solution in the temperature range 113-140 degree leads to formation of phenylacetic acid in a much lower yield than would be expected in the case of a mechanism involving decomposition of an intermediate alpha -keto hydroperoxide with formation of phenylacetic acid and benzaldehyde. It is conclused from data on variation of the composition of the reaction products with increase of the dibenzyl ketone concentration in o-dichlorobenzene, and especially in presence of cobalt naphthenate, that the decrease of phenylacetic acid yield is due to increase of the degree of radical decomposition of the alpha -keto hydroperoxide.
