Conclusions 1. The existence of rigid and labile donor-acceptor complexes in the 2,6-diphenyl-1,4-benzoquinone-ethylenediamine system, the stability of which is determined by the rate of consumption of the 2,6-diphenyl-1,4-benzoquinone, has been demonstrated by means of ESR spectroscopy. 2. The fact that cyclohexadienone is formed in the 1,4-addition of ethylenediamine to 2,6-diphenyl-1,4-benzoquinone has been confirmed by NMR spectroscopy. 3. The nature of the hydrocarbon fragment of the diamine has a substantial effect on the direction of its reaction with 2,6-diphenyl-1,4-benzoquinone.
