After drying over sodium sulfate and concentration to vacuum the remaining residue is subjected to chromatography over silica gel. Using a benzene-ethyl acetate mixture (19 1) there is eluated 900 mg of 6-chloro-1,2a-methylene-A -pregnadiene-17o-ol-3,20-dione-17-acetate, which upon recrystallization from isopropyl ether melts at 200° to 201°C. [Pg.423]

This procedure has been used to effect the following reductions at ca. 150° bromobenzene to benzene (89%), iodo-benzene to benzene (95%), 1-chlorobutane to n-butane (95%), 2-chloro-2-methylbutane to 2-methylbutane (32%), and isopropyl chloroacetate to isopropyl acetate (63%). [Pg.105]

The reactions are carried out at room temperature, except in the case of 2-methyl-5-isopropyl-acetophenone, which requires heat. The products are nearly insoluble in ether, benzene, petroleum ether and carbon tetrachloride, but dissolve in water or alcohol with decomposition. They cannot be recrystallised and hence impurities are removed by washing first with benzene and then with ether. The compounds are more or less unstable, some commencing to decompose at once and others not showing marked decomposition for a period of two weeks. Decomposition gives a reddish sticky mass with a strong lachrymatory, action and an odour like that of chloro-ketones. The following table shows the substances which have been obtained. [Pg.57]

The following alkoxypyrazines have been prepared from the corresponding dichloropyrazines and alkoxide ions 2,3-dimethoxy-5,6-dimethyl(and diphenyl) (797) 2,3-dibenzyloxy (sodium benzyl oxide in benzyl alcohol at reflux for 24 hours (883)] [but 23-dichloropyrazine with sodium hydride and benzyl alcohol in xylene gave l,4-dibenzyl-2,3-dioxo-l,2,3,4-tetrahydropyrazine)(988)] 2-chloro-5-methoxy (838) 2,5-diethoxy-3,6-dimethyl (872) 2methanolic sodium methoxide refluxed for 2 h) 2,5-dimethoxy-3-phenyl (817) 2-chloro-5-methoxy(and ethoxy)-3,6-diphenyl (817) 2,5-dimethoxy-3,6-dimethyl (and diisopropyl) (844) 2,5-dimethoxy-3-isopropyl-6-methyl (methanolic potassium methoxide at reflux for 6 days) (844) 2(5)-s-butyl-3-chloro-6-ethoxy-5(2)-isobutyl (93) 2-chloro-6-methoxy (838, 883) 2,6-dimethoxy (reflux for 8h) (832) 2,6-diethoxy (reflux for 14 h) (883) 2-benzyloxy-6-chloro (1 equiv. of sodium hydride and benzyl alcohol in benzene at reflux) (832) 2,6-dibenzyloxy (5 equiv. of sodium benzyloxide in benzene at reflux gave 70%) (832) and 3,5-dimethoxy-2-methyl (535). [Pg.136]

Preparation. - Fluorophosphines have been obtained from the reactions of the related chlorophosphines with trimethyl tin fluoride. Phenyl(isopropyl)-fluorophosphine has been resolved via a chiral amine-palladium(II) complex, providing the first example of the resolution of a free fluorophosphine chiral at phosphorus. This compound racemises at 20 °C in benzene solution over six hours. The neat compound rapidly decomposes by redox disproportionation. The same approach has been used for the resolution of the related chloro-phosphine, but the optically active compound could not be liberated unchanged from the crystallised diastereoisomeric palladium complex. The dihalo-genophosphines... [Pg.23]
