alkane,alkane series,methane series,paraffin series,paraffin- a series of non-aromatic saturated hydrocarbons with the general formula CnH(2n+2) monoamine- a molecule containing one amine group (especially one that is a neurotransmitter) ptomain,ptomaine- any of various amines (such as putrescine ...
This reaction was achieved by devising a mixed heterogeneous photocatalyst in situ prepared from Cu/TiO2 and Au/TiO2. The mixed photocatalytic system enabled the rapid N-alkylation of pharmaceutically relevant molecules, the selective mono- and di-alkylation of primary amines, and the non-symmetrical...
A new effective catalytic system consisting of [Cp*IrCl2]2/K2CO3 (Cp*=pentamethylcyclopentadienyl) for the N-alkylation of primary amines with alcohols has been developed. As an example, the reaction of aniline with benzyl alcohol in the presence of [Cp*IrCl2]2 (5.0 mol%Ir) and K2CO3 ...
Transbenzylation reactions are also used on occasion for deprotection as seen from the reaction shown in equation (119).187 In 1937, Ipatieff and Pines188 found that the ease of dealkylation of alkylbenzenes in the presence of AlCl3 at 65–80 °C to give the corresponding alkane decreased ...
Figure 6:N-alkylation of (hetero)aromatic amines using (hetero)aromatic and aliphatic alcohols. (a) General reaction conditions: aniline derivative (1 mmol), benzyl alcohol (1.2 mmol),1(3 mol%),t-BuOK (0.75 equiv.) and toluene (2 ml), 80 °C, 24 h. (b) Conversio...
Representative references which illustrate some of the early processes in forming ring alkylated aromati amines are: British Pat. No. 414,574 discloses the reaction of aniline with various olefins, e.g., cyclohexene and alcohols,e .g., butanol in the presence of a neutral or weakly acidic ...
