C. Thiete 1,1-dioxide. A sample of 3-chlorothietane l,l-d1ox1de (8.0 g, 0.057 mol) Is dissolved In dry toluene (300 ml) (Note 7) In a 500-mL, twonecked, round-bottomed flask equipped with a reflux condenser, magnetic stirrer, heating mantle (or silicone oil bath), and thermometer. The reaction Is heated to 60° C and tri ethyl amine (28.7 g, 0.28 mol, 39,5 ml) Is added through the condenser. The reaction mixture Is stirred for 4 hr and triethyl-amine hydrochloride is removed by filtration and washed with toluene (100 mL), Toluene is removed on a rotary evaporator and the residue is recrystallized from diethyl ether-ethanol (Note 8) to give a white solid (4.5-4.8 g, 75-81 ) mp 49-50°C (llt mp 52-54°C).

Uses. Nearly half the ethyl alcohol produced in petrochemical plants (not the stuff fermented for human consumption) is used as a chemical intermediate in the manufacture of ethyl acrylate, ethyl amines, ethyl acetate (when you pop the cap on nail polish remover, you smell ethyl acetate), ethylene chloride, glycol ethers, acetaldehyde, and acetic acid. However, you will see in the chapters on acetaldehyde and acetic acid, there are now more competitive routes than those based on ethyl alcohol. 

The submitters dried the ethylamine and pyridine by distillation over potassium hydroxide pellets. The submitters used 600 ml. of petroleum ether, 113 g. (2.50 moles) of ethyl-amine, and 158 g. (2.00 moles) of pyridine to which was added 135 g. (1.00 mole) of sulfuryl chloride in 250 ml. of petroleum ether. In the United States ethylamine is sold in 100-g. quantities in sealed-glass vials (Eastman Organic Chemicals) or as the compressed gas in cylinders (Matheson Gas Products). The checkers used the contents of a freshly opened vial (without distillation) for each run as a matter of convenience. The checkers used either ])entane or petrolonm eth(M (b.p. 38-51°). 

One of the early syntheses of meperidine (75) starts with the double alkylation of phenylacetonitrile with the bischloro-ethyl amine, 72. The highly lachrimatory nature of this material led to the development of an alternate synthesis for the intermediate piperidine (73). Alkylation of phenylacetonitrile with two moles of 2-chloroethylvinyl ether leads to the intermediate (69). This is then hydrolyzed without prior isolation to the diol, 70. Treatment with thionyl chloride affords the corresponding dichloro compound (71). This last is then used to effect a bis alkylation on methylamine, in effect forming the piperidine (73) by cyclization at the opposite end from the original scheme. Saponification to the acid (74) followed by esterification with ethanol affords the widely used analgesic meperidine (75) substitution of isopropanol for ethanol in the esterification affords properidine (76). ... 

It easily forms double compds, such as boron trifluoride etherate. Another compd, boron tri fluoride-mono ethyl amine, BFa— C2H6NH2 is wh to pale tan flakes, melting at 88—90°.

The transfer of a carbamate moiety to olefins has been documented only in very few cases, using activated unsaturated substrates. For example, Yoshida and Inoue reported the selective (100%) formation of 1-ethoxyethyl N,N-dialkylcarbamate esters by the reaction of C02 (5 MPa) with ethyl vinyl ether and secondary amines R2NH (R = Me, Et) in the absence of any catalyst (Equation 6.11) [85]. 

The silyl enol ether may be obtained from the Fluka Chemical Corp., 255 Oser Avenue, Hauppauge, NY 11788. Alternatively, it may be prepared by the following modification of the procedure of Walshe and co-workers.2 The Walshe procedure is followed exactly with 36 g (0.30 mol) of acetophenone, 41.4 g (0.41 mol) of tri ethyl amine, 43.2 g (0.40 mol) of chlorotri-methylsilane, 60 g (0.40 mol) of sodium iodide, and 350 nt of acetonitrile. After extraction, the organic layer is dried over potassium carbonate and then concentrated with a rotary evaporator under reduced pressure. The crude product is a mixture of 97% of the desired silyl enol ether and 3% of acetophenone, as shown by gas chromatography. The crude product is distilled in a Claisen flask at a pressure of about 40 mm. After a small forerun (ca. 3...

The contributions made by these pathways in proton transfer between amines and their conjugate acids have been determined [193] and the results are shown in Table 13. The rate coefficient kt refers to the direct proton transfer mechanism and k2 is for proton transfer through a solvent bridge. The available evidence for carbon acids suggests that proton transfer occurs directly between acid and base and an intervening solvent molecule is not involved [123,194]. This evidence is mostly based on the magnitude of the solvent isotope effect, and results for reactions involving nitroparaffins, acetals, and diazocompounds have been reviewed [123]. In a different approach to this question, the rate expression for the acid catalysed decomposition of ethyl vinyl ether in water/dimethyl-sulphoxide was measured [195] and shown to consist of two terms (111).
