An effective method has been developed for Rh(III)‐catalyzed direct vinylation of arenes to give functionalized styrenes, using vinyltriethoxysilane as a convenient and inexpensive vinyl source. A wide variety of substrates, including 1‐aryl‐2‐pyrrolidinones, anilines, benzamides and ketones, were compatible with this reaction. Moreover, this method can be applied to the two‐step synthesis of functionalized

An efficient Rh(III)-catalyzed direct ortho-C–H olefination of acetanilides with vinylacetate was developed. This protocol provides a straightforward pathway to a series of (E)-2-acetamidostyryl acetates, giving access to indole derivatives following a simple hydrolysis/cyclization process.
