Treatment of the ω-alkenyl substituted cyclohexane-1,3-dione enol derivatives (1), (11), and (13) with rhodium trichloride trihydrate leads to the corresponding resorcinol derivatives (2), (12), and (15) respectively. By contrast, the RhCl3.3H2O catalysed isomerisations of the related enol ethers (5) and (9) instead produce the dienones (6) and (10) respectively.
