(DMSO)-promoted catalyst-free oxidative C–N coupling and C–O coupling under oxidant-free conditions are outlined. This protocol is operationally simple and leads to various functionalized substituted imidazoles or oxazoles in good yields. To date, a very limited number of oxidation protocols have been established, where DMSO acts solely as a catalyst or an oxidant or both. In this report, DMSO is not only used
概述了
二甲亚砜 (
DMSO) 促进的无催化剂氧化 C-N 偶联和无氧化剂条件下的 C-O 偶联。该方案操作简单,并且以良好的产率产生各种官能化的取代
咪唑或
恶唑。迄今为止,已经建立的氧化方案数量非常有限,其中
DMSO 仅充当催化剂或氧化剂或两者兼而有之。在本报告中,
DMSO不仅用作C-N/C-O
偶联剂,还用作这些氧化转化所需的氧化剂。因此,我们所证明的
DMSO 促进的无催化剂偶联转化有能力引领氧化偶联领域的新维度。
