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.
用三水合三水合铑处理ω-烯基取代的环己烷-1,3-二酮烯醇衍生物(1),(11)和(13)得到相应的间苯二酚衍生物(2),(12)和(15)分别。相反,相关的烯醇醚(5)和(9)的RhCl 3 .3H 2 O催化的异构化分别产生二烯酮(6)和(10)。
