A very simple and convenient reaction for 1,3-diketone preparationfrom carboxylic acids and aromatic ketones in TFAA/TfOH system is described. When the beta-phenylpropionic acids were used as starting materials, they initially gave 1-indanones and then underwent further acylation with the formation of 2-(beta-phenylpropionyl)-1-indanones as the main reaction products. In addition, the application

A rapid and efficient method for ‘one-pot’ synthesis of pyrazoles from (hetero)arenes and carboxylic acids via successive formation of ketones and β-diketones followed by heterocyclization with hydrazine has been developed. The utility of the RCOOH/TfOH/TFAA acylation system for intermediate production of ketones and 1,3-diketones is a key feature of this approach. The preliminary evaluation of the
