Application

2-Methylpentane is mainly used in studies involving the functionalization of aliphatic C–H bonds using different carbene insertion processes to form C–H insertion products. The metal-free Ritter-type amination reaction of tertiary C–H bond using iodic acid as an oxidant in the presence of N-hydroxyphthalimide has also been reported.

We report the solvent-dependent dynamics of carbonyl site exchange for Fe(CO)3(η(4)-norbornadiene) (FeNBD) in a series of linear and nonlinear alkanes. The barrier to exchange is very low (∼1.5 kcal/mol), and the resulting carbonyl dynamics are rapid enough to lead to
