Highly Selective Hydroiodination of Carbon-Carbon Double or Triple Bonds

Iodine is an element that exhibits characteristic features of heavy halogen, and several compounds containing iodine constitute important synthetic intermediates due to synthetically easy manipulation. To utilize iodine units for organic synthesis, a highly regio- and stereoselective introduction of iodine to versatile building blocks is significant, and a lot of research works for the selective introduction of iodine to alkynes or alkenes have been conducted. In this review article, we describe regio- and stereoselective hydroiodination to multiple bonds of building blocks, and its synthetic applications as key intermediates to construct several important compounds in organic chemistry.
