Phenoxazines, in particular N-arylated phenoxazines, represent an increasingly important scaffold in the material sciences. Moreover, the oxygen-gas-mediated dehydrogenative phenochalcogenazination concept of phenols has been developed and exemplified for X = sulfur and recently for X = selenium and tellurium. The smallest chalcogen, X = oxygen, is herein exemplified with various functional groups
吩恶嗪,特别是 N-芳基化
吩恶嗪,代表了材料科学中越来越重要的支架。此外,已经开发并举例说明了
氧气介导的
酚类脱氢
酚硫属化合物的概念,例如 X =
硫,最近 X =
硒和
碲。最小的
硫属元素,X = 氧,在本文中以在同样微弱的
氧气氛下的各种官能团为例。
