Abstract
Diphosphorus tetraiodide (P2I4) is the only known stable halogeno derivative of diphosphine, which possesses a unique affinity for oxygen and thus behaves as a mild, efficient deoxygenating and dehydrating agent in the presence of various functionalities. In this brief article, potential aspects of P2I4 as organic reagent have been surveyed with an emphasis on the coverage of recent works.
