PHENOXY-PROPENE OXIDE (122-60-1) Combustible liquid (flash point >176 F/ >80°C). Forms unstable peroxides in air and light unless inhibitor is maintained in adequate concentrations. Contact with amines, strong acids, and strong bases may cause polymerization with spattering and the liberation of heat. Reacts violently with strong oxidizers, permanganates, peroxides, ammonium persulfate, bromine dioxide, acyl halides. Attacks some forms of plastics, coatings, and rubber.

The degradation products of GOS were 1,3-dimethyl pyrogallol (HI), 2-(2 ,6 dimethoxy phenoxy)-2-propenal (Vni), 2-(2, 6 -dimethoxy phenoxy)-3-hydroxypropanal (XII), and GOS-Dimer. These products show that the reaction includes oxidative polymerization and the cleavage of -0-4 ether linkage following the alkyl-phenyl cleavage. This depolymerization pathway of GOS is also similar to that of SOS (Table I). 

Combining thianthrene radical ion(l+) with free radicals to produce thianthrenium salts has also been achieved. Decomposition of various cumene hydroperoxides (83MI6) and of azobis(2-phenoxy-2-propane) (85MI1) gave 5-arylthianthrenium ions together with 5-(propen-2-yl)thianthrenium perchlorate in the latter case. 

To a 125-ml Claisen flask is added 40.0 gm (0.71 mole) of powdered potassium hydroxide. The flask is heated to 50°C in an oil bath while the distillation receiver is cooled with Dry Ice. Then 18.0 gm (0.085 mole) of 2-bromo-l-phenoxy- 1-propene is added drop wise to the hot alkali while heating at 17 mm. A vigorous reaction occurs at 90°C, and the product distills over rapidly. The crude allene is dried over sodium sulfate and then fractionally distilled to afford 5.5 gm (50%), b.p. 45.5-46.2°C (2 mm), n2D5 1.5490, d 1.0127.

The results from the reaction of ( )-2-butene and 3-phenoxy-l-propene using (5)-1-phenyl-ethanamine as the homochiral amine are shown in Table 4. Low yield and/or low asymmetric induction were generally observed. Lack of regioselectivity was observed with 1-butene. 

Various forms of radiation have been used to produce ions in sufficient quantitites to yield neutral products for subsequent analysis. In principle, it should be possible to use intense beams of UV below ionization threshold for this purpose. To date, however, efforts to collect neutrals from resonant multiphoton ionization (REMPI) have not succeeded. In one experiment, 1 mbar of gaseous -propyl phenyl ether was irradiated at room temperature with a 0.1 W beam of 266 nm ultraviolet (from an 800 Hz laser that gives 8 n pulses) concurrent with a 0.5 W beam at 532 nm. The beams were intense enough not only to ionize the ether in the mass spectrometer, but also to excite it so that it expels propene. After several hours of irradiation < 10% of the starting material remained. Production of carbon monoxide and acetylene (decomposition products of the phenoxy group) could be detected by infrared absorption spectroscopy, but the yield of neutral propene (as measured by NMR spectroscopy) was infinitesimal. 

Methoxyphenoxycarbonyl)-phenoxy]hexyl methacrylate was first polymerized by GTP using l-methoxy-l-(tri-methylsiloxy)-2-methyl-l-propene as the initiator and tris(dimethylamino)sulfonium bifluoride as the catalyst in THF at room temperature (Eq. 13) [47]. 

To a suspension of (i )-3,3 -diiodobinaphthol 197a (240 mg, 0.44 mmol) in toluene (7 ml) was added a solution of zirconium tetra-t-butoxide (135 mg, 0.37 mmol) in toluene at 25 °C. After stirring for 30 min, a mixture of propanol (179 mg, 2.9 mmol) and water (13 mg, 0.74 mmol) in toluene (7 ml) was added. After stirring for 30 min at 25 °C, the solution was cooled to 0 °C. To the mixture was added a solution of aldehyde 209 (728 mg, 3.7 mmol) in toluene (3.5 ml), followed by a solution of ( )-l-trimethylsilyloxy-l-phenoxy-l-propene (992 mg, 4.4 mmol) in toluene (3.5 ml) at 0°C. After stirring for 30 min at the same temperature, the solution was quenched with saturated aqueous NaHCOj. The layers were separated, and the aqueous phase was extracted with dichloromethane. The combined organic extracts were washed with brine and dried with sodium sulfate. The solvent was...
