Abstract

An N-heterocyclic stannylene :Sn(NONAd) (NONAd = [O(SiMe2NAd)2]2−, Ad = 1-adamantyl), reacts rapidly with 2,4,6-tricyclohexylphenyl azide (TCHP)N3, affording a stannaimine, (NONAd)Sn=N(TCHP). Solutions of (NONAd)Sn=N(TCHP) react immediately with carbon dioxide (CO2) to give a [2+2]-cycloaddition product, which, upon heating, subsequently engages in a metathesis process to give [Sn(NONAd)(μ-O)]2 and the bulky isocyanate, (TCHP)NCO.
