Article abstract of DOI:10.1007/BF00807099

p-Benzoquinone (1) reacts with dialkylamines 2a-d to 2-dialkylamino-p-benzoquinones 3, 2,5-bis-dialkylamino-p-benzoquinones 4, 2-dialkylamino-8-hydroxydibenzofuran-1,4-quinones 5, and in pyridine also to 2-dialkylamino-5-p-hydroxy-phenoxy-p-benzoquinones 6. A method affording almost exclusively 3 has been developed which is also applicable to compounds 2e-h.
