Description

Application

5-Vinylthianthrenium tetrafluoroborate is a crystalline, shelf-stable vinylating reagent developed by the Ritter Lab. Despite the great functionality of the vinyl group for diversification of target compounds, the selective installation of this moeity has remained challenging. 5-Vinylthianthrenium tetrafluoroborate can perform this otherwise challenging transformation with a broad scope of substrate, including the N-vinylation of heterocycles, vinylation of aryl boronic acids, and the annulation of cyclic and heterocyclic substrates. Additionally, this reagent can be used to enable palladium catalyzed cross-coupling reactions. The functionality of 5-vinylthianthrenium tetrafluoroborate enables the usage of vinyl groups as a versatile tool for further functionalization of many substrates and is a functional tool for many snythetic pathways.
