The complex 4-cht)> (cht= cycloheptatriene) and give 5-C7H8N2C6H4NO2-p>> (1) which is deprotonated on alumina to give syn- and anti-isomers of the hydrazone complex 4-C7H6NN(H)C6H4NO2-p>> (2); the C7H6NN(H)C6H4NO2-p is detached from the metal on reaction with N(O)Me3*2H2O.By contrast, free cycloheptatriene and in water yield 4-hydroxy-5-p-nitrophenylazobicyclohept-2-ene.
