A Cheap and Efficient Oxidant (n-Bu)₄NNO₃-Enabled C(sp²)– and C(sp³)–H Olefination at Room Temperature

Abstract

To further promote the widely practical application of C−H activation, developing green and mild reaction conditions has invariably been the objective of researchers, especially when it comes to remote C−H activation reactions. Herein, we report a new cheap and powerful (n-Bu) 4 NNO 3 oxidant. This oxidant is efficient and universal for Pd(II)catalyzed sp 2 and sp 3 C−H olefination and allows the reaction to be carried out at room temperature. Because of this, we attempted to make C−H functionalization more economical and environmentally benign.
