EFFECT OF CONFORMATION ON THE REACTIVITY OF α-ARYLAMINOANTHRAQUINONES. REACTION OF 1-ARYLAMINOANTHRAQUINONES WITH THE VILSMEIER COMPLEX

1-Phenylaminoanthraquinone reacts with the Vilsmeier complex mostly with the formation of the N-(1-antraquinonyl)-N-phenyl-N',N'-dimethylformamidinium salt.The introduction of a methyl group at the nitrogen atom or at position 2 of anthraquinone or two methoxy groups at positions 2 and 5 of the phenyl group makes it possible to formylate the latter quantitatively at the para position. 1-(2,6-Dimethylphenylamino)-anthraquinone does not enter into the reaction at all.The effect of the conformation of the nitrogen atom and rotation of the phenyl on account of steric hindrances on the direction of the reaction at the N and C4' atoms was examined for the case of these and other substituted 1-phenylaminoanthraquinones.It was concluded that sterically unhindered 1-arylaminoanthraquinones have a structure close to planar in solutions.
