Application

4-Isopropylbenzoic acid (cuminic acid) was used in the synthesis of three new triorganotin carboxylates bearing methyl, butyl and phenyl substituents at tin, respectively. The products were fully characterized by spectroscopic and thermal techniques, with regard to the coordination number of tin atom, in solution and in the solid state.

Pseudomonas putida F1 utilizes p-cymene (p-isopropyltoluene) by an 11-step pathway through p-cumate (p-isopropylbenzoate) to isobutyrate, pyruvate, and acetyl coenzyme A. The cym operon, encoding the conversion of p-cymene to p-cumate, is located just upstream of the cmt operon, which encodes
