2-dicarboxylic acid (III) derived by hydrolysis of the photoadduct of phenanthrene with dimethyl maleate. Reaction of the dichloride (II) with N-bromosuccinimide, followed by chromatography on alumina, gave 1,2-dichloro-1,2-dihydrocyclobuta-[I]phenanthrene (IV). Treatment of the product (IV) with enneacarbonyldi-iron afforded tricarbonylcyclobuta-[I]phenanthreneiron (V). Oxidative decomposition of compound
1,2-二氯-1,2,2a,10b-四氢环丁[ I ]菲是通过菲与反式二氯乙烯的光环加成反应以及水解产生的1,2-二羧酸(III)的二氯双脱羧反应制得的菲与马来酸二甲酯的光加合物的合成。使二氯化物(II)与N-溴琥珀酰亚胺反应,然后在氧化铝上进行色谱分离,得到1,2-二氯-1,2-二氢环丁-[ I ]菲(IV)。用烯羰基二铁处理产物(IV),得到三羰基环丁-[ I ]菲铁(V)。在环戊二烯存在下,化合物(V)与铈(IV)离子氧化分解,得到内-加合物(VI)。
