Asymmetric β-functionalization of secondary amine with CH2Cl2 on a chiral NCN pincer Rh complex.

Functionalization of a β-C–H bond of a secondary aliphatic amine was accomplished using NCN pincer Rh complex 1 with a chiral bis(oxazolinyl)phenyl ligand. Complex 1 underwent asymmetric alkylation of dicyclopentylamine with CH 2 Cl 2 to form azametallacycle complex 2 . Additionally, the reaction of 1 with triethylamine in CH 2 Cl 2 resulted in the formation of ammonium ylide complex 3 via C–N bond formation. [ABSTRACT FROM AUTHOR]
