Why are amines basic, but amides are not basic? a. Amides can delocalize the positive charge through resonance while amines can't. b. Amines have more conformational flexibility. c. Amides are more polar than amines. d. The amide lone pair is conjugated w ...
spectrochemical analysis/ solid-state primary aliphatic aminesammonium amidesinfrared spectroscopyoctadecylaminefluid-phaseThe infrared spectra of primary alkylamines largely belong to one of two different types as found out by a systematic data search. This search was motivated by observing before an ...

Alternatively, the bis-amines are obtained by alkylation of the thiocolchicine nitrogen with suitable halogen- or tosyl-derivatives. In rare cases the bis-amines are prepared from the corresponding bis-amides through reduction with boranes. The compounds with different G1 and G2 are prepared in ...
The ob‐ tained ANN model could predict a peptide sequence containing 41 aminoacids with an error less than 0.03. Half of the test set was predicted with less than 3% of error and more than 95% of this set was predicted with an error around 10%. These results showed that the ANN ...
CYP2E1 availability and thus potency comparing rat, hamster and man resulted in different experimental results in both in vivo and in vitro studies suggesting induced hamster S9 being slightly more potent than induced rat S9 to activate nitrosamines including small N-nitrosodialkylamines [17,21,22...
The invention furthermore relates to a process for the preparation of compounds of the formula I. Compounds of the formula I in which Y=SO2, were prepared by i) reacting the pyridine-2-carboxylic acid derivatives or the corresponding esters of the formula 11 with the amines of the formula...
