Ethylenediamine protonated
WebA total of 10 mmol (1.02 g) of N,N,N ′-trimethyl ethylenediamine was taken in 50 mL methanol . To the methanolic solution, about 0.30 g (10 mmol) of paraformaldehyde was mixed. The reaction mixture was then refluxed for 3 h. A total of 10 mmol (2.06 g) of 2,4-di-tert-butylphenol was added to it. The resulting mixture was again refluxed for ... WebWhether mono-(ethylenediamine)Co(III) species were present initially is impossible to say, as their reduction to Co(II) would be expected under the conditions of the final acidified reaction mixture [11]. Both "free" Co(II) and ethylenediamine (protonated) were isolated during the chromatography but they could also have arisen
