secondary amines has been studied. The synthetic procedure was developed in order to synthesize a series of new N,N-disubstituted o-aminophenols. The interaction of 3,5-di-tert-butyl-o-benzoquinone with dimethylamine leads to 2-(N,N-dimethylamino)-4,6-di-tert-butyl-phenol, which is oxidized in the reaction medium by the parent 3,5-di-tert-butyl-o-benzoquinone forming spirocompound 4,5′,6,7′-tetra-te
的3,5-二-相互作用叔丁基- ö苯醌与仲胺进行了研究。为了合成一系列新的N,N-二取代的邻氨基酚,开发了合成方法。的相互作用3,5-二-叔丁基- ö苯醌与二甲胺导致2-(Ñ,Ñ二甲基氨基)-4,6-二-叔丁基苯酚,其在反应介质中通过氧化父3,5-二-叔丁基- ö醌形成spirocompound 4,5',6,7'-四-叔丁基-3'-甲基-3' ħ-螺[1,3-苯并二恶唑-2,2'-[1,3]苯并恶唑]。
