Highly selective acylation of dimethylamine mediated by oxygen atoms on metallic gold surfaces
Xu, Bingjun Zhou, Ling Madix, Robert J. Friend, Cynthia M.
"Chemical Equation Presented" Completely coupled: The acylation of dimethylamine through coupling to formaldehyde occurs with almost 100 % selectivity at low coverage of adsorbed O atoms on metallic gold and with a low activation energy. Oxygen creates an active intermediate (CH3) 2N(a), which attacks the carbonyl carbon of the aldehyde (see picture). A general mechanistic framework for efficient and selective acylation of amines promoted by Au is established.
Effects of Carbon-Bound Deuterium on the Affinities of Acetaldehyde-1-d and N-Methylformamide-1-d for Solvent Water
Wolfenden, Richard Kirkman, Sue
With deuterium present in the formyl group, the equilibrium constant for transfer of N-methylformamide from chloroform to D2O at 25 deg C was encanced by factor of 3.1 +/- 0.15 percent, as estimated independently by proton magnetic resonance and by double-labeling experiments in which 14C and 3H were incorporated alternatively into the methyl group.The distribution coefficient of acetaldehyde-1-d between D2O and the vapor phase, on the other hand, differed from that of acetaldehyde by less than 0.5percent.
