Ureido-functionalized compounds play an indispensable role in important biochemical processes, as well chemical synthesis and production. Isocyanates, KOCN particular, are the preferred reagents for ureido functionalization of amine-bearing compounds. In this study, we evaluate potential urea a reagent to graft groups onto amines at relatively low temperatures (<100 °C) aqueous media. Urea i...

The reactivity of phosphenium dication [(Ph3P)2C-P-NiPr2](2+), 1(2+), towards pyridine N-oxide (O-py) has been investigated. The resulting oxophosphonium dication [(Ph3P)2C(NiPr2)P(O)(O-py)](2+), 2(2+), was surprisingly stabilized by a less nucleophilic O-py ligand instead of pyridine (py). This compound was then identified as an analogue of the elusive Criegee intermediate as it underwent oxyg...
