A novel electrochemical esterification of alkynes for the synthesis of esters was developed in which diols and their derivatives were used as the partners. This method is green as it is catalyst-free, oxidant-free, and additive-free and shows atom-economy. This is the first example of an electrochemical reaction via cleavage of carbon-carbon triple bonds. Meanwhile, this is also the first example of a carbon-carbon triple bond cleavage reaction of alkynes with diols. This journal is
INTEGRATED PROCESS FOR THE PRODUCTION OF BENZOATE PLASTICIZERS

, (2016/04/20)
The invention relates to a process that integrates the oxidation of toluene to benzoic acid with the production of benzoate plasticizers. Toluene is fed to an oxidation vessel in the presence of oxygen and an oxidation catalyst wherein benzoic acid serves as the solvent for the oxidation. The crude benzoic acid produced is not purified and is then reacted with an alcohol in the presence of an esterification catalyst to produce the crude benzoate ester. The oxidation catalyst, esterification catalyst, and other impurities can be mostly removed from the crude benzoate ester in subsequent washing and filtering steps. The benzoate esters produced through this method can be made in fewer steps with both yields and purities above 80%.
N-Acyltetrazole as an intermediate for preparation of carboxylic acid derivatives

A new mild and very efficient procedure for preparation of acid derivatives via N-acyl-5-phenyltetrazole is reported. The yields are high at -10°C and purification is simple but, because of the thermal instability of the intermediate, a certain amount of corresponding oxadiazole arises if the reaction is carried out at higher temperature.

A series of monopercarbonates were obtained from tert-butyl hydroperoxide and the chloroformates of diethylene (propylene) monoethers.The kinetics of their thermal dissociation at 110-140 deg C in organic solvents were investigated.The products from the homolysis of the peroxy esters were investigated, and it was established that the free radicals which form react preferentially with the hydrogen of the C-H bond in the organic fragment of the initial monoperoxy carbonate or its decomposition products.A scheme for the transformations of the obtained free-radicalparticles is proposed on the basis of the kinetic investigations and the balance of the thermolysis products.
