Methoxyethyl benzene

The enantiomerically pure complex (5 )-tricarbonyl(t 6-1-methoxy-2-methoxymethylben-zene)chromium(0), available from the enantiomerically pure 2-methoxybenzaldehydo complex34, led to the diastereomerically pure [j76-l-methoxy-2-[(JR)-r-methoxyethyl]benzene derivative which gave, after decomplexation, 1-methoxy-2-[(/ )-l -methoxyethyl]benzene. This is, as yet, the sole reported example.

Karasek et al. [32] determined phenols in soils by extraction with a mixture of benzene and water modified to pH 10 by the addition of 2-methoxyethyl-amine. The phenol in the extract was identified and determined by gas chromatography using a variety of detectors, including flame ionisation, electron capture and mass spectrometry.

Methyltriphenylphosphonium heptahydrodiborate(l —) is a white, crystalline, air-sensitive compound. It is moderately stable at room temperature, but decomposes readily at 100°. It is soluble in methylene chloride, chloroform, and 1,1,2,2-tetrachloroethane, but insoluble in benzene, pentane, tetrahydrofuran (THF), diethyl ether, dimethyl ether, and diglyme [bis(2-methoxyethyl) ether]. 

Another control experiment was run to further confirm the significance of the cation-pi interaction in these bibracchial lariat ether model complexes. In this case, a diaza-18-crown-6 derivative was prepared in which a 2-phenylethyl pi-donor sidearm was attached to one nitrogen and a 2-methoxyethyl sigma donor was attached to the other <2002CC1808>. The structure is illustrated as 14, above. The solid-state structure of the 14 KI complex showed the typical apical solvation of the ring bound cation. In this case, however, one apex was solvated in the pi-fashion (benzene) and the other by the oxygen sigma donor. 

The rate of fluoride exchange is considerably enhanced in the presence of polar solvents e.g. MeCN or bis(2-methoxyethyl)ether, but not by benzene or diethyl ether the rates in MeCN at 25 C were comparable with the gas-solid reactions at 150 C [683]. Similarly, rapid exchange was noted between gaseous CO F j and solid MF 3 (M = La or Tl), HgF j, Hg jF or TIF at 150 C under similar conditions, AgF was largely unreactive [682], It is of interest to note that the pattern of reactivity towards fluoride exchange does not parallel the catalytic effect of the metal fluorides upon the reaction between COF j and F j (see Section 13.7.3). 

A solution of 2,4-dinitrophenylhydrazine (0.20 g, 1 mmol) in dry bis(2-methoxyelhyl) ether (6 tnL) was treated first with a solution of 2,3-diphenyleyclopropenone (0.206 g, 1 mmol) in dry bis(2-inetlioxyethyl) ether (2 mL) and then TFA (0.5 mL). The original red solution did not turn yellow, but after a few minutes, the product began to crystallize out. After 3 h, the product was filtered off and washed with dry bis(2-methoxyethyl) ether and benzene. Recrystallization (MeNOj) gave brown crystals yield 0.29 g (75%) nip 263 C (dec.).
