| Abstract: | N, N-Dimethylformamide dimethyl acetal transforms an allylic OH group, which is part of a tetracyclic hydrocarbon in a unique elimination reaction into a 5.5.5.5]fenestradiene ( 2b → 4 ). In topologically selective reactions of this diene 4 with Fe2(CO)9,], the Fe(CO)4(η2-diene)] and the Fe(CO)3(η4-diene)] complexes 8 and 9 , respectively, are formed by complexation on one side of the diene moiety, whereas complexation on the other side leads to a Fe(CO)2(Cp)] complex 10 . |
