- Abstract
Au- and Rh-based heterogeneized catalytic systems have been prepared and analyzed. Their efficiency has been evaluated for the cycloisomerization of γ-acetylenic carboxylic acids leading to valuable γ-alkylidene γ-butyrolactones. Bulk AuO3 was found to be a valuable and easy-to-handle catalyst for selective transformations, whereas [C6mim][AuCl4] presented a high activity and Au/β-zeolite was recyclable.
