Nucleophilicity toward ketenes: rate constants for addition of amines to aryl ketenes in acetonitrile solution.
Second-order rate constants (k(Nu)) have been measured for the addition of amines to ketenes 4-6 in acetonitrile solution by the laser flash photolysis technique. These ketenes are formed from a photochemical Wolff rearrangement of diazoketones 1-3, respectively. For all diazoketones studied, the presence of amines as nucleophiles in the reaction medium results in the formation of an intermedia...
متن کاملBiogenic amines in sea products
Sea food products are being processed through various techniques, i.e. chilling and freezing, heating, irradiating, and curing; regard to the condition of processing, formation of biogenic amines are probable, as raw materials are usually rich in respective precursors. Fermented fish products are among the most vulnerable items to this challenge, these products due to their nutritious value are...
متن کاملPalladium catalyzed N-alkylation of amines with alcohols
An iron oxide immobilized palladium catalyst was prepared for the N-alkylation of amines with alcohols under base and organic ligand free conditions. Applying the optimized reaction conditions, the coupling reactions of amines and alcohols with various structures could be realized with up to 99% isolated yields. The catalysts were studied by XRD, BET, and XPS and the mechanism was studied by DF...
متن کاملIron-catalysed oxidative amidation of alcohols with amines.
A new iron-catalysed oxidative amidation of differently substituted benzylic alcohols with mono- and di-substituted amines was developed.
متن کاملEfficient iron-catalyzed N-arylation of aryl halides with amines.
A practical and promising protocol was developed for N-arylations of various amines with differently substituted aryl halides. The processes are efficiently promoted by the catalyst system involving the environmentally benign Fe2O3 and the universal ligand L-proline. The versatility, convenient operation, low cost, and environmental friendliness, in combination with the high yields, render this...
