Diethylammonium chloride, reaction

Diethylammonium chloride, reaction with chloroform to give 1,1,3-trichloro- -nonane, 45,104 Diethylazelate, 46, 31 Diethylbenzene as solvent for decomposition of diphenyliodonium-2-carboxylate in preparation of... [Pg.127]

A solution of 0.54 g. (2 mmoles) of ferric chloride hexahydrate and 0.33 g. (3 mmoles) of diethylammonium chloride (Note 1) in 5 g. of methanol is added to a solution of 11.2 g. (0.1 mole) of 1-octene (Note 2) and 0.42 g. (2 mmoles) of benzoin (Note 3) in 36 g. (0.3 mole) of chloroform (Note 4). The resulting homogeneous mixture is introduced into a Carius tube of about 100-ml. capacity. Air is displaced by dropping a few pieces of dry ice into the tube (Note 5). The tube is sealed (Note 6), heated to 130°, kept at that temperature for 15 hours, cooled to room temperature (Note 7), and opened. The contents of the tube are transferred to a separatory fuimel, and the tube is rinsed with about 10 ml. of chloroform. The reaction mixture is washed with 40 ml. of water. The aqueous solution is extracted with 10 ml. of chloroform, and the extract is added to the original chloroform layer. Solvent is distilled at atmospheric pressure (bath temperature up to 130°). The distillation flask is allowed to cool, and distillation is continued at 25 mm. (bath temperature up to 120°) (Note 8). The flask is cooled again, and distillation is continued to dryness at 0.1 mm. (bath temperature up tc 150°), giving crude l,l,3-trichloro- -nonane (19.4 g.) as a yellow oil, b.p. 60-85° (0.1 mm.), 1.4650. The purity of this... [Pg.53]

The origin of the majority of rhenium—rhenium quadruple bonds can be traced directly to the parent Re2Clg anion. Several routes to the octachloro-dirhenate(III) ionic complex have been compared (42). The method of choice is the reaction of trirhenium nonachloride with molten diethylammonium chloride (12). Yields of up to 65% are attainable when the reaction mixture is extracted with hydrochloric acid and the anion is precipitated as the salt of a large cation (i.e., tetrabutylammonium cation). [Pg.222]

Diethylamino)ethyl dextran (DEAE dextran) is synthesised by reaction of dextran with (2-chloroethyl)diethylammonium chloride in the presence of NaBH4 in an alkaline solution at 85-90 °C (Fig. 45). [Pg.260]

Separation of the reaction products is accomplished by reaction of ammonium chloride with diethyl ami no to form ammonia and diethylammonium chloride, which is soluble in chloroform ... [Pg.108]

The octachlorodirhenate(III) anion, [Reads]2- has been prepared in several ways, including (a) reduction of perrhenate ion in acid solution with molecular hydrogen at high temperature and pressure 1 (b) reduction of perrhenate ion with hypophos-phorus acid, in a solution of constant boiling hydrochloric acid 1,2 (c) displacement of the carboxylate ligands in Re2-(OOCR)4Cl2 with chloride ion in concentrated hydrochloric acid 1,2 (d) reaction of trirhenium nonachloride in molten diethylammonium chloride.3... [Pg.82]

The acetylene corners of molecular square 37 can bind with cations in a tweezer fashion. Silver cations added to these corners (using silver triflate) form modified macrocycles which host a variety of neutral bases (pyridine, pyrazine, phenazine, and dipyridyl ketone) <19981C5595, 1998JA9827>. The reaction by-product (diethylammonium chloride) of molecular square 39 is difficult to remove and is always detected in the H NMR. This strong affinity is attributed to a tweezer interaction between the comer acetylene groups and the ammonium cation <2004OM4382>. [Pg.1066]

The reactions of the poly(alkylene chlorophosphate)s with diethylamine were completed after two hours. Most of the diethylammonium chloride byproduct could be removed from the polymers by cooling their dichloromethane solutions to -78 °C and filtering. The remaining diethylammonium chloride was removed by stirring a dichloromethane solution of the dry polymer over anhydrous potassium carbonate for 24 h to convert the diethylammonium chloride to diethyl amine, and then evaporating the solution to dryness. [Pg.256]
