3-(2,2-Dimethylpropyl)-1-cyclobutene-1-carboxylic acid → 3-(2,2-Dimethylpropyl)cyclobutane-1-carboxylic acid

Participants

Reaction Steps

3-(2,2-Dimethylpropyl)-1-cyclobutenecarboxylic acid (163 g) and tetrahydrofuran (1300 mL) were mixed. After an addition of 5 w/w % rhodium on activated carbon (8.2 g) to the mixture, the mixture was stirred at RT for 35 hr under hydrogen atmosphere (1 atm). The 5 w/w % rhodium on activated carbon was filtered off and the filtrate was concentrated in vacuo to give the title compound (175.56 g) as a crude product.
