Benzyltrimethylammonium Chloride

Benzyltrimethylammonium chloride [56-93-9J M 185.7, m 238-239 (dec). A 60% aq soln was evapd to dryness under vac on a steam bath, and then left in a vac desiccator containing a suitable dehydrating agent. The solid residue was dissolved in a small amount of boiling absolute EtOH and pptd by adding an equal volume of diethyl ether and cooling. After washing, the ppte was dried under vac [Karusch J Am Chem Soc 73 1246 7957]. [Pg.131]

Nucleophilic substitutions of benzyl chloride or benzyltrimethylammonium chloride as electrophiles with Ph3P or Bu3P as nucleophiles have been performed with accurate control of the power and temperature by use of a monomode reactor. The results were carefully compared under similar conditions with microwave or A activation [85] (Eq. (30) and Tab. 3.11). [Pg.86]

Where reactivity is low, as for example with non-activatcd haloarenes, soliddiquid conditions are to be preferred over liquid liquid conditions and better yields are frequently obtained when TDA-1 is used as the catalyst instead of a quaternary ammonium salt [28]. Although not activated to nucleophilic attack, 2-chlorophenol reacts with ethanol under solid liquid conditions with microwave irradiation in the presence of benzyltrimethylammonium chloride to produce the ether in 70% yield [44], It is possible that the procedure has potential for further exploitation. [Pg.31]

Unless otherwise indicated, all reactions were run under solid-liquid conditions in a nitrogen atmosphere and water was azeotropically removed during the course of the reaction. Initial product isolation was accomplished by rapid filtration of the reaction mixture through a silica gel column followed by concentration of the organic phase. Data for BTEAC liquid-liquid conditions and for TBAHS from ref 39. Benzyltrimethylammonium chloride,... [Pg.178]

The use of mixtures of sodium hydroxide and benzyltrimethylammonium chloride or tetrabutylammonium bromide failed to enhance the DPGE alkylation of HEC by the in situ formation of the corresponding quaternary ammonium hydroxide phase transfer catalyst. These quaternary ammonium halides are too soluble in aqueous /-butyl alcohol and are preferentially extracted into the organic phase. Mixtures of benzyltrimethylammonium hydroxide and sodium acetate were also ineffective in enhancing the DPGE alkylation of HEC for the same reason, namely preferential solubility of benzyltrimethylammonium acetate in the organic phase. [Pg.42]

Dauricine (116) reacted under phase-transfer conditions (benzyltrimethylammonium chloride, benzene, diethyl sulfate, 15% aqueous NaOH, 45 min reflux), giving the ethyl ether in 60% yield (589). [Pg.196]

In the second stage, the above prepolymer is prereacted with liquid epoxide resin in the presence of benzyltrimethylammonium chloride as a catalyst. The crosslinking occurs as a result of the reaction of the remained epoxy groups with 4,4 -diamino-diphenylmethane added [90]. [Pg.52]

Triphenyltrifluoro tellurium and excess phosphorus pentafluoride in dichloromethane form triphenyldifluorotellurium(VI) hexafluorophosphate, which, upon treatment with sodium fluoride, reverts to triphenyltrifluoro tellurium, and upon treatment with benzyltrimethylammonium chloride yields triphenylchlorodifluoro tellurium4> 5. [Pg.706]

The laboratory interfacial condensation of a mixture of iso- and terephthalyl chlorides and 4,4 -biphenyldisulfonyl chloride with bis-phenol A is best carried out with methylene chloride as the solvent, as shown in Table III. A surfactant is required, and the best found for our work was benzyltrimethylammonium chloride (BTAC) (Table IV). The detailed mechanism of this polycondensation was investigated and will be presented in a later publication. [Pg.726]

Ioplex and Biolon are commercial names of polyelectrolyte complexes composed of poly(4-vinyl-benzyltrimethylammonium chloride) (PVBMA) and poly(sodium styrenesulfonate) (NaSS). PEPP and PAA are poly(ethylenepiperazine) and poly(acrylic add), respectively... [Pg.40]

Sodium metal (69 g., 3 g. atoms) is introduced into flask A, which had been flushed previously with nitrogen (Note 2). Ethanol (1.2 kg.) (Note 3) is added at such a rate that a continuous reflux is maintained. After the sodium is completely dissolved, the solution is allowed to cool to room temperature. During this period the benzyltrimethylammonium chloride is prepared. [Pg.5]

Although sodium amalgam is unreactive toward phenyltrimethylammonium chloride, benzyltrimethylammonium chloride is cleaved to toluene and trimethylamine. A similar reaction is responsible for the reductive ring opening of N, N-dimethyltetrahydroquinolinium chloride to 2-propyl-A, A-dimethylaniline [123]. [Pg.1157]

An aqueous solution of the reagent is prepared by dissolving 0.12 mole each of benzyltrimethylammonium chloride and sodium cyanide in 40-50 ml. of water. An alkyl halide added with stirring and cooling is soon converted in part into the nitrile and a benzyltrimethylammonium halide which acts as an emulsifying agent. After the emulsion has been heated on the steam bath for 1-6 hrs., the nitrile is obtained, usually in good yield. [Pg.760]
