资源简介：
Carbon dioxide can be readily converted quantitatively and under
mild conditions into the aryl isocyanate and symmetrical carbodiimide via a metathetical reaction involving a zwitterionic titanium
imide (nacnac)TiNAr(CH3B(C6F5)3) (nacnac- = [ArNC(tBu)]2CH,
Ar = 2,6-iPr2C6H3). The metathetical process to generate isocyanates allows also for facile formation of sterically demanding aryl
isocyanide, by a deoxygenation route. Labeling studies using
enriched 13CO2 are also described.
