Hydrogen abstraction from organotin di- and trihydrides by N-heterocyclic carbenes: a new method for the preparation of NHC adducts to tin(<scp>ii</scp>) species and observation of an isomer of a hexastannabenzene derivative [R₆Sn₆]

Abstract

<italic>N</italic>-Heterocyclic carbenes are shown to cleanly abstract dihydrogen from organotin di- and trihydrides to intermediately form the reactive stannylene species [R₂Sn] and [R′SnH], respectively, which undergo further reactions.
