Abstract

The complex [Fe(CO)34-cht)] (cht = cycloheptatriene) and [N2C6H4NO2-p] [BF4] give [Fe(CO)35-C7H8N 2C6H4NO2-p}] [BF4] (1) which is deprotonated on alumina to give syn- and anti-isomers of the hydrazone complex [Fe(CO)34-C7H6NN(H)C 6H4NO2-p}] (2); the C7H6NN(H)C6H4NO2-p is detached from the metal on reaction with N(O)Me3·2H2O. By contrast, free cycloheptatriene and [N2C6H4NO2-p] [BF4] in water yield 4-hydroxy-5-p-nitrophenylazobicyclo [4.1.0]hept-2-ene.
