excellent halides_Methylammonium halide - Wikipedia
Methylammonium halides are organic halides with a formula of CH3NH3X, where X is Cl, Br or I. Generally they are white or light colored powders. They are used primarily to prepare light absorbing semiconductors for perovskite solar cells.
excellent halides_Nickel-Catalyzed Reductive Methylation of Alkyl Halides ...Methylation of unactivated alkyl halides and acid chlorides under Ni-catalyzed reductive coupling conditions led to efficient formation of methylated alkanes and ketones using methyl p-methyl tosylate as the methylation reagent.Moderate to excellent coupling yields as well as excellent functional group tolerance were observed under the present mild and easy-to-operate reaction conditions.
