Abstract: We herein report the use of phenyl trimethylammonium iodide (PhMe3NI) as a safe, nontoxic, and easy-to-handle reagent for an absolutely monoselective N-methylation of amides and related compounds as well as for the N-methylation of indoles.… read more here.

Abstract: A palladium/nickel catalyzed selective N–H/C–H methylation of amides by using peroxides is described, providing N-methylation products and C-methylation products in moderate to good yields. In this procedure, peroxides play a dual role, serving as both… read more here.
