6- methyl-1,1,3-trichloro

In a more complex type of reaction, propene reacts with methyl trichloro-acetate under the catalytic influence of cyclopentadienylmolybdenum tricarbonyl or cyclopentadienyliron dicarbonyl dimers to give 4-methyl-2,2 -... [Pg.348]

Methyl />-acetylbenzoate has been prepared by the esterification of -acetylbenzoic acid with methanol in the presence of hydrogen chloride,6 by the hydrogenation of methyl -trichloro-acetylbenzoate in the presence of a palladium on calcium carbonate catalyst,6 and by the air oxidation of methyl / -ethyl-benzoate.4...

With the V0(0 ter-C Hj)j—Al2(C2Hj)3Clj catalytic system and with ethyl tri-chloroacetate acting as a promoter , polyethylene with very narrow MWD was obtained (Q = 2.1 to 2.6 values from fractionation data). Similar behaviour was observed for a modified Carrick-like catalytic system prepared from a soluble vanadium compound, Sn(CgH5)4 and AlBrj, in the presence of methyl trichloro-acetate as promoter .

In addition to chloroform, many other compounds containing the trichloro-methyl group, CI3C-, show marked physiological action. Thus trichloro-acetaldehyde or chloral hydrate, Cl3C CH(OH) (p. 342), and trichloro-tertiary-butanol or chloretone, CUC CfCHaliOH, are both hypnotics. Similarly, tribromo-ethanol or avertin, BraC-CHjOH, has strong anaesthetic properties. [Pg.91]

Successful results have been obtained (Renfrew and Chaney, 1946) with ethyl formate methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec.-butyl and iso-amyl acetat ethyleneglycol diacetate ethyl monochloro- and trichloro-acetates methyl, n-propyl, n-octyl and n-dodecyl propionates ethyl butyrate n-butyl and n-amyl valerates ethyl laurate ethyl lactate ethyl acetoacetate diethyl carbonate dimethyl and diethyl oxalates diethyl malonate diethyl adipate di-n-butyl tartrate ethyl phenylacetate methyl and ethyl benzoates methyl and ethyl salicylates diethyl and di-n-butyl phthalates. The method fails for vinyl acetate, ieri.-butyl acetate, n-octadecyl propionate, ethyl and >i-butyl stearate, phenyl, benzyl- and guaicol-acetate, methyl and ethyl cinnamate, diethyl sulphate and ethyl p-aminobenzoate.

The para and ortho positions of phenols condense at the carbonyl group of acetone to make bisphenols, eg, bisphenol A, 4,4 -(l-methylethyhdene)bisphenol [80-05-07]). If the H atom is activated, CICH— compounds add to the carbonyl group in the presence of strong base chloroform gives chloretone (l,l,l-trichloro-2-methyl-2-propanol [57-15-8]). [Pg.94]

Cyclization. Constmction of ben2otrifluorides from aHphatic feedstocks represents a new technique with economic potential. For example, l,l,l-trichloro-2,2,2-trifluoroethane [354-58-5] and dimethyl itaconate [617-52-7] form 4-methoxy-6-trifluoromethyl-2JT-pyran-2-one [101640-70-4] which is converted to methyl 3-(trifluoromethyi)ben2oate [2557-13-3] ixh. acetjdene or norbomadiene (125).

A/-Trimethoxybora2ines are available from reaction of dichloroboranes and 0-methyl-X,X-his(trimethylsilyl)hydroxylamine (eq. 31). The B-trichloro-bora2iQes undergo substitution reactions at the B atoms to give B-tri(/ f -butoxy)- or B-tri(/ f2 -but5i)-A/-trimethoxybora2iaes (101)... [Pg.265]

In the presence of an alkali metal hydroxide at about 50°C, chloroform condenses with acetone to give l,l,l-trichloro-2-methyl-2-propanol, [57-15-8] ie, chlorobutanol, chloretone, or acetone—chloroform (9,10). Chlorobutanol is a white crystalline substance with a campborlike odor its sedative, anesthetic, and antiseptic properties have given the compound some importance in the pharmaceutical industry.

An acid-catalyzed substitution of a 6-oxo group on 2-aminopteridine-4,6-dione with hydrogen chloride in alcohols (65-100°, 3 hr, 80% yield) represents a convenient synthesis of the 6-alkoxy analogs. The reaction proceeds also with pteridine-2,4,6-trione and its 1-methyl and 1,3-dimethyl derivatives. While methoxylation of 2,4,7-trichloro-quinoline gives about equal amounts of 2- and 4-substitution, acid-catalyzed hydrolysis gives specific reaction at the 2-position only. ... [Pg.195]
