Up to the present there has been no doubt about the possibility of selective hydrogenation of the side chain double bond in alkenylfurans [1]. In particular, catalysts consisting of palladium on carriers (SrCO3 [2], BaSO4 [3, 4]) have been used. They have been used to hydrogenate compounds with the double bond at various positions in the side chain [2–4], but not alkenylfurans with the double bond at the 2, 3 position. Having synthesized compounds of this latter type [5], the present authors attempted to hydrogenate selectively 2-(3-methylbuten-2-yl) furan and 2-(2,3-dimethylbuten-2-yl) furan, but it was unexpectedly found that with Pd/BaSO4 and at atmospheric pressure hydrogenation was non-selective, and gave the corresponding alkyltetrahydrofurans. Hydrogen uptake rate fell uniformly, and slowed down greatly when hydrogenation was complete.
