Abstract
Carbocationic intermediates play an important role in the construction of complex molecules, from biosynthetic pathways in nature to the synthesis of natural products by organic chemists. Herein, a brief introduction that surveys C–C bond forming reactions of vinyl carbocations is highlighted. The discussion of experimental work commences with the development of a main group-catalyzed approach towards accessing vinylated esters through the trapping of vinyl carbocations with silyl ketene acetals. Next, a Claisen-type rearrangement is discussed, which is a result of trapping vinyl carbocations with allyl ethers to form an allyl vinyl oxonium intermediate in situ that can subsequently rearrange. Finally, the last method that is highlighted includes the development of an asymmetric C–H insertion reaction of vinyl carbocations to forge bicyclic products in a highly enantioselective fashion.
