An efficient, direct carbamoylation and amination of quinoline N-oxides with formamides to access 2-carbamoyl and 2-amino quinolines has been developed through copper-catalyzed C-C and C-N bond formations via cross-dehydrogenative coupling reactions. The reaction proceeds smoothly over a broad range of substrates with excellent functional group tolerance under mild conditions. Mechanistic studies suggest that the reaction is initiated by formamide radical or decarbonylative aminyl radical formation in the presence of TBHP, according to the different substituent on the N atom of formamide.
METHODS AND COMPOSITIONS FOR INHIBITING VINYL AROMATIC MONOMER POLYMERIZATION
-
, (2013/03/26)
Methods and compositions are provided for inhibiting the polymerization of a vinyl aromatic monomer, such as styrene monomer, during elevated temperature processing thereof or during storage or shipment of polymer containing product. The compositions comprise a combination of a quinone methide derivative A) and a phenol compound B). The methods comprise adding from about 1-10,000 ppm of the combination to the monomer containing medium, per one million parts of the monomer.
