Catalytic C1 Alkylation with Methanol and Isotope‐Labeled Methanol

Abstract A metal‐catalyzed methylation process has been developed. By employing an air‐ and moisture‐stable manganese catalyst together with isotopically labeled methanol, a series of D‐, CD 3 ‐, and 13 C‐labeled products were obtained in good yields under mild reaction conditions with water as the only byproduct.
