Multicomponent synthesis of 4H-pyran and 4H-chromene in alcohols using nickel catalysts, indicating enhanced efficiency.
A highly efficient and convenient multicomponent one-pot synthesis of 4H-pyran/4H-chromeneanalogues has been demonstrated via acceptorless dehydrogenative annulation (ADA) of alcohols employing newly designed Ni(II)–ONO pincer complexes as catalysts. A discrete...
