A novel and efficient synthesis of ortho- and para-benzoquinones of cardanol derivatives was carried using catalytic system MeReO3-H2O2. The effect of the presence of bromine atoms on the selectivity of the oxidation was also studied. It was observed that the regio-selectivity of the reaction depends on the nature and on the substitution pattern of the substituents.

Carbon radicals derived from the esters of several types of thiohydroxamic acids have been trapped in a number of different ways.Particular attention has been paid to carbon-carbon bond formation by addition to suitably activated ethylenic linkages.Carboxylic acids can be conveniently converted into homo- and bishomo-acids by free radical chemistry based on thiohydroxamic esters.In a coda the tautomerism of the thiohydroxamic acids have been examined by physical methods.It is confirmed that the esters used are derivatives of the thione tautomer.
