Iridium(III)-induced isomerization of 2-substituted pyridines to N-heterocyclic carbenes.
Steric strains (F-strain or front-strain) in the acid-base interaction between the Lewis acid [TpMe2Ir(C6H5)2] and 2-substituted pyridines Lewis bases, are responsible for the stabilization of the C-adducts (2) of the respective pyridine carbene tautomers over the expected N-adducts.
