Recent advances in positional-selective alkenylations: removable guidance for twofold C–H activation
TLDR
Various easily removable or transformable directing groups utilized in the transition metal-catalyzed oxidative C–H alkenylations are discussed in this review until February 2017.Abstract:
The transition metal-catalyzed transformation of otherwise inert C–H bonds into substituted alkenes offers a versatile tool for the synthesis of value added olefinic molecules. Recent developments in the directing group assisted C–H activation approach ensured high levels of positional selectivity. A vast number of coordinating groups have been utilized in directed C–H alkenylation, which are often not removable after the desired transformation. However, the concept of easily removable or traceless directing group strategy overcomes this limitation and enables site-selective C–H alkenylation of relevance to academia and the practitioners in industry. Various easily removable or transformable directing groups utilized in the transition metal-catalyzed oxidative C–H alkenylations are discussed in this review until February 2017.read more
