Over more than five decades, Alain Krief’s career has encompassed many contributions to chemistry, notably in his innovative work in the areas of organic synthesis and the use of inorganic and organic reagents, as well as his work on bioorganic chemistry and applications of information technology in chemistry. His research on the synthesis of cyclopropanes, including chrysanthemic acid and other pyrethroids, and the uses of selenium compounds in organic synthesis, have been of particular importance and have found widespread applications. In addition, his roles in international collaborations in research and his leadership of the International Organization for Chemical Sciences in Development from 2009 to 2020 have marked his strong commitment to the importance of chemistry as a science for the benefit of society and a contributor to the goal of sustainable development.1 Introduction2 A Spectrum of Research3 Leadership of the International Organization for Chemical Sciences
