Anthracene and dihydroanthracene react with (C5Me5)Fe(CO)2Br and AlCl3 to give a mixture of [(C5Me5)Fe(η6-9,10-dihydroanthracene)]+X– and [(C5Me5)Fe(η6-1,2,3,4-tetrahydroanthracene)]+X–(60:40) whereas under identical conditions, (C5H5)Fe(CO)2Cl gives only [(C5H5)Fe(η6-9,10-dihydroanthracene)]+X–.
蒽和二氢蒽与反应(C 5我5)的Fe(CO)2 Br和的AlCl 3,得到的混合物[(C 5我5)的Fe(η 6 -9,10-二氢蒽)] + X -和[( ç 5我5)的Fe(η 6 -1,2,3,4- tetrahydroanthracene)] + X -(60:40),而在相同条件下,(C 5 H ^ 5)的Fe(CO)2氯仅给出[( ç 5 ħ 5)的Fe(η 6-9,10-二氢蒽)] + X –。
