Stable sulfenes have been isolated by treating methanesulfonyl chloride, with triethylamine or trimethylamine in acetonitrile solvent at -40°C (165,166). These stable sulfenes undergo 1,2 cycloaddition with enamines to form the expected thietanes (trimethylenesulfones). [Pg.241]

Aliphatic sulfonyl chlorides that have a-hydrogen substituents, react with simple tertiary amines, such as trimethylamine, to generate sulfenes or perhaps their amine adducts 446). These species are suggested by the incorporation of one (but not more) deuterium atoms on reaction of sulfonyl chlorides with deuterated alcohols and triethylamine (447-450). A 2 1 adduct of sulfene and trimethylamine with proposed sulfonyl-sulfene structure could be isolated (451). [Pg.402]

Photolysis of aryl azides in amine solution, with a tertiary amine as cosolvent to promote stabilization of the singlet nitrene, has met with some success. For example, the yield of 2-piperidino-3 W-azepme. obtained by the photolysis of phenyl azide in piperidine, is increased from 35 to 58% in the presence of A A /V. /V -tetramethylethylenediamine (TMLDA).180 Also, an improved yield (36 to 60 %) of A,(V-diethyl-3W-azepin-2-amine (38, R = Et) can be obtained by irradiating phenyl azide in triethylamine, rather than in dicthylaminc, solution.181 Photolysis (or thermolysis) of phenyl azide in TMEDA produces, in each case, 38 (R = Et) in 40% yield.181 In contrast, irradiation of phenyl azide in aniline with trimethylamine as cosolvent furnishes jV-phenyl-377-azepin-2-amine (32, R = Ph) in only low yield (2%).35... [Pg.147]

Recently Tanabe and co-workers have found that several alcohols were smoothly and efficiently tosylated using tosyl chloride/triethylamine and a catalytic amount of trimethylamine hydrochloride as reagents.6 Compared with the traditional method using pyridine as solvent, this procedure has the merit of much higher reaction rates, and it avoids the side reaction in which the desired tosylate is converted into the corresponding chloride. [Pg.42]

Irradiation of 8 with trimethylamine 11 yields the regiospecific adducts 13, 17 and 2027. The reaction of 8 with triethylamine 10 in either hexane or acetonitrile solution (>290 nm) results in the formation of a single adduct 14 (24% yield) accompanied by comparable amounts of 17 (15%) and also 20 (78%)28 (equation 3). Regiospecific addition of triethylamine to a-methylstyrene 9 is also observed to give 15 (32%), 18 (11%) and 21 (8%)26 (equation 3). [Pg.686]

As expected, DABCO is a much stronger base than triethylamine, has two ionization potentials separated by several electron-volts, and is more easily oxidized than trimethylamine. What is unusual about DABCO is that the in-phase combination of the nonbonded pairs is the HOMO, the lowest IP is lower than that of trimethylamine, and the next higher IP is higher than that of trimethylamine. Explain. [Pg.259]

As initiators, common peroxides, such as dicumyl peroxide, di-benzoylperoxide can be used, but also photo initiators have been reported. Photoinitiating systems are the combinations of benzo-phenone with amines, such as n-butylamine, trimethylamine and triethylamine (43). [Pg.226]

Material 1 was also treated with 3-bromopropyltrichlorosilane to yield a propyl tether with a bromo-head group (4). Substitution with either trimethylamine or triethylamine to form the corresponding quaternary ammonium species, followed by ion exchange with potassium perruthenate afforded the catalytic species (5) and (6) respectively. The black solid 5 was found to be an equally efficient catalyst for the oxidation reactions and 6 was found to be a more highly active recoverable and reusable... [Pg.801]

Sun et al. further investigated the photoinduced electron transfer reactions of C6o and triethylamine, both in deoxygenated solution and air saturated solution [79], Three types of cycloadducts of fullerenes 33 and 92a-b were obtained, whereas the formation of the monoalkylated l,2-dihydro[60]fullerene 29 as described by Liou et al. [230] in the reaction of trimethylamine and /V,/V-dimcthy-laniline with C6o, was not observed (see Fig. 32). [Pg.708]

Amines may be regarded as derivatives of ammonia, NH3, in which one to three of the H atoms have been replaced by hydrocarbon groups. When these groups are aliphatic groups of which none contains more than six C atoms, the compound may be classified as a lower aliphatic amine. Among the more commercially important of these amines are mono-, di-, and trimethylamine mono-, di-, and triethylamine dipropylamine isopropylamine butylamine dibutylamine diisobu-tylamine cyclohexylamine and dicyclohexylamine. Example structures are given in Figure 15.1. [Pg.324]

In another example, 2-methoxyperfluoro-3,4-dimethyl-4-ethylhex-2-ene reacts with pyridine or CsF, or with water in the presence of triethylamine, forming perfhioro-2,5-dihydro-2,3,4,5-tetramethylfurans (79USP983009). The reaction occurs via the intermediate formation of the O-anion, involved in intramolecular nucleophilic attack of the O-nucleophilic center at the difluoromethylene group. Perfluoro-3,4-dimethylhex-2-ene behaves analogously with methanol in the presence of pyridine (or triethylamine, or trimethylamine). [Pg.162]
