Carbon dioxide induced metathesis of C
N and C
O triple bonds of methyl isocyanide and carbon monoxide
Abstract
Metathesis of the CN triple bonds of the methyl isocyanide ligands of Ni2(CNMe)3(dppm)2, (1), [dppm = bis(diphenylphosphino)methane] and the C
O triple bonds of the carbonyl ligands of Ni2(CO)2(CNMe)(dppm)2, (3), can be achieved thermally or photochemically via oxygen atom transfer from carbon dioxide.
