Abstract
This Special Issue would cover the hot topics on recent synthetic interest in iodine reagents and related chemistry as well as the unique characteristics of hypervalent iodine compounds. The excellent reviews by the experts and eminent researchers engaged in the recent advances, i.e., preparations, reactions, and mechanistic studies of hypervalent iodine compounds, and their utilizations as reagents and organocatalysts in controlled reactions for synthesizing useful organic molecules, such as pharmaceutical compounds and organic materials, are provided in this Special Issue.
