Untersuchungen �ber Chinone, 10. Mitt. Zur Reaktion vonp-Benzochinon mit sekund�ren aliphatischen Aminen
摘要:
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.

High-pressure kinetics of the reaction of p-benzoquinone with di-n-butylamine in some aprotic solvents
The kinetics and the volume of activation of the title reaction to form 2-dibutylamino-p-benzoquinone in 1,2-dicholoroethane and acetonitrile, –54 ± 2 and –67 ± 2 cm3/mol respectively, strongly support a reaction scheme in which ionic species are formed prior to the rate-determining step which is the second attack by the amine.
在1,2-二氯乙烷和乙腈中分别形成–54±2和–67±2 cm 3 / mol的标题反应形成2-二丁基氨基-对苯醌的反应动力学和活化体积,强烈支持了以下反应方案在速率确定步骤之前形成哪些离子物种,这是胺的第二次攻击。
