Reactivity of Polar Organometallic Compounds in Unconventional Reaction Media: Challenges and Opportunities

Developing new green solvents in designing chemical products and processes or successfully employing the already existing ones is one of the key subjects in green chemistry and is especially important in organometallic chemistry, which is an interdisciplinary field. Can we advantageously also use unconventional reaction media in place of current harsh organic solvents for polar organometallic compounds? This microreview critically analyses the state of the art with regard to this topic and showcases recent developments and breakthroughs that are becoming new research directions in this field. Because metals cover a vast swath of the Periodic Table the content is organized into three sections discussing the reactivity of organometallic compounds of s-, p- and d-block elements in unconventional solvents.
