The authors focus on the methylation of amines with carbon dioxide and hydrogen molecule (H2). They mention that two catalysts formed from ruthenium acetylacetonate [Ru(acac)3] and 1,1,1-tris(diphenylphosphinomethyl) ethane, enabled the conversion of carbon dioxide and carboxylic acid derivatives into N,N-dimethylaniline and N-methylaniline. They mention that methylation reaction with formamide and methanol formed intermediates, which then reduced to a methylated product.

Kohlendioxid kann zur selektiven reduktiven Methylierung sekundärer und primärer aromatischer und aliphatischer Amine verwendet werden. Vielfältige tertiäre Amine werden durch Einwirkung von CO2 und käuflichen Silanen in hohen Ausbeuten erhalten. Die Katalysereaktion toleriert Nitril ‐ , Olefin ‐ , Ether ‐ , Ester ‐ und Hydroxygruppen in den Substraten. [ABSTRACT FROM AUTHOR]
