CuFe2O4 superparamagnetic nanoparticles were utilized as a recyclable heterogeneous catalyst for the direct synthesis of chemical structures containing both phenol ester and benzothiazole moieties via cross dehydrogenative coupling reactions. Several substrates were reactive towards the transformation in the presence of the nano catalyst, including benzaldehyde, benzyl alcohol, dibenzyl ether, 2-oxo-2-phenylacetaldehyde, and 2-iodo-1-phenylethanone. This nano catalyst displayed higher catalytic efficiency than many homogeneous and heterogeneous catalysts. The nano CuFe2O4 was easily isolated by using a magnet, and reutilize numerous times without a remarkable deterioration in catalytic performance. To our best knowledge, these reactions were not previously reported in the literature.

Inexpensive ceric ammonium nitrate (CAN) is an efficient oxidant for the Pd-catalyzed substrate-directed o-benzoxylation and decarboxylative o-aroylation processes. In the presence of CAN, the reaction of directing arenes with carboxylic acids resulted in o-benzoxylated products, whereas a decarboxylative o-aroylation occurred by using innodataalpha-keto acids, which led to the formation of o-aroylation products.

A copper-catalyzed oxidative esterification of 2-carbonyl substituted phenols from the alcohol oxidation level is described. This protocol represents direct access to a range of 2-carbonylated aryl benzoate derivatives, which are important building blocks in the synthesis of natural and pharmacological compounds.
