derivatives with substituents in 2- and 6-positions has been synthesized. A number of compounds were investigated by dynamic NMR spectroscopy. Restrictedrotation was observed in 3-methyl-2-neopentylbenzoic acid and its derivatives. Thermodynamic and Arrhenius parameters were obtained for the restrictedrotation of the neopentyl group. An additional Me group in 3-position causes a COOMe group in 2-position
