This article provides a short review of the chemistry of stannylenes and their derivatives, including the preparation, spectroscopic properties, molecular structure and reactivity of the various species. The organometallic chemistry of Sn(II) is far less explored than that of its much more common Sn(IV) counterpart. Organometallics of main group metals have become increasingly important in recent years, which prompted us to present an overview of the situation regarding the case of Sn(II).
Sn(II) organometallics; stannylenes; unsaturated Sn-Sn bonds
