Hypervalent Iodine Compounds
Hypervalent Iodine Compounds. Weaker and longer than covalent linkages, hypervalent bonds are the result of a linear threecenter, fourelectron (3c4e) electronic distribution (hypervalent model). Hypervalent iodine reagents are useful synthetic tools due to their low toxicity, ready availability, and ease of handling.
