Formation of Carbon-Oxygen Bond Mediated by Hypervalent Iodine Reagents Under Metal-Free Conditions

Hypervalent iodine reagents are a class of non-metallic oxidants that have been widely used in the construction of several sorts of bond formations. This surging interest in hypervalent iodine reagents is essentially due to their very useful oxidizing properties, combined with their benign environmental character and commercial availability from the past few decades ago. Furthermore, these hypervalent iodine reagents have been used in the construction of many significant building blocks and privileged scaffolds of bioactive natural products. The purpose of writing this review article is to explore all the transformations in which carbon-oxygen bond formation occurs by using hypervalent iodine reagents under metal-free conditions.
