Amines => imides

This preparation illustrates a general method for the synthesis of N-methylalkylamines. The submitters have used it to prepare N-methylbutylamine (Note 4) and N-methylallylamine, and the checkers have used it to prepare N-methylisopropylamine (80%), N-methylisobutylamine (67%), N-methyl-fert-butylamine (52%), and N-methyl-2-methoxyethylamine (55%). Secondary amines are useful as starting materials for the synthesis of 1,1-disubsti-tuted hydrazines and asymmetric amine imides. 

Diesel fuel detergents are usually organic amines, imides, succinimides, polyalkyl amines, or other polyamine-type compounds. These compounds function by dispersing and solubilizing deposit-forming compounds into the fuel. Some detergents can also remove existing deposits from fuel injection system parts. 

A much more elegant synthesis of polyimides by amine-imide exchange is based on the reaction of iV-ethoxycarbonyl phthalimides with amino acids to yield phthaloyl substituted amino acids [106]. Thus, reaction of N,N-bis(ethoxycarboxy)pyromellitimide with p, p-oxydianiline in NMP at room... 

Unlike amines, imides do not have basic properties in water solution the electron pair of nitrogen is partly delocalized over the carbonyl groups,... 

Dihenzyl carbonate, DABCO, DMA, 135°C, 79% yield. Aryl amines, imides, and acids are also benzylated using this method. ... 

The azo-compound (248) rearranges thermally to the pyrazole (249). The 1-pyrazoline (250) is formed from the thioketen 5-oxide Bu Pr C=C=SO and 2-diazopropane.The allyl chloride H2C=C(COPh)CH2Cl reacts with 1,1-dimethylhydrazine to yield the pyrazolidine derivative (251). Numerous betaines (252 R, R, R = H or Me) have been prepared by the action of aromatic aldehydes on the appropriate pyrazolidinones. Treatment of diethyl acetylmalonate with 1,1-dimethylhydrazine affords the amine-imide (253). ... 

Campamio. [Union Camp] Amido-amines/imid lines. 

Functionalized PPE may he prepared hy allowing PPE to react with a species that contains both a C=C bond and a reactive moiety, such as hydroxyl, acid, anhydride, amine, imide, epoxy, etc. Examples of species of the acid and anhydride type include maleic anhydride, fumaric acid, and citraconic anhydride. ... 

The Akzo Nobel alkyl ammonium carboxylate (zwitterionic)/SDBS (molar ratio 4 1) surfactant mixture is DR in both water and ethylene glycol/water systems. However, better DR results were obtained at lower temperatures by a new alkyl amin-imide zwitterionic in both water and ethylene glycol/water solutions [Zhang et al., 2005b], This was attributed, in part, to the presence of the oleyl chain, which enhances low-temperature solubility. 

Amines are suitable nucleophiles in the Tsuji-Trost reaction, with the use of simple amines, imides, azides, sulfonamides and heterocyclic amines having been reported." In fact, one of the first examples of the catalytic version of the Tsuji-Trost reaction involved the use of aliphatic amine nucleophiles. Subsequently these important nucleophiles have been used extensively in synthesis.
