2-chloro hexachloroethane

In the presence of catalysts, trichloroethylene is readily chlorinated to pentachloro- and hexachloroethane. Bromination yields l,2-dibromo-l,l,2-trichloroethane [13749-38-7]. The analogous iodine derivative has not been reported. Fluorination with hydrogen fluoride in the presence of antimony trifluoride produces 2-chloro-l,l,l-trifluoroethane [75-88-7] (8). Elemental fluorine gives a mixture of chlorofluoro derivatives of ethane, ethylene, and butane. [Pg.23]

Efficient synthesis of 2-chlorofuran is best achieved by decarboxylation of 2-chlorofuran-5-carboxylic acid (63JGU1397) or via the lithium derivative of furan. When furan or 3-bromofuran were treated in turn with ethyl-lithium and hexachloroethane, 2-chlorofuran (48%) or 3-chlorofuran (54%) was formed, uncontaminated by any polychlorinated products (73SC213). Chlorodesilylation of ethyl 5-trimethylsilyl-2-furoate with sul-furyl chloride in acetonitrile gave the 5-chloro ester in —85% yield (91MI4). [Pg.305]

Preparations and reactions of some mono(trialkylsilyl)phosphines, which derived from bis(trialkylsilyl)phosphines, were described in Sections II.A and II.B. Other preparative methods of mono(trialkylsilyl)phosphines are described in Reference 10. Reactions of some mono(trialkylsilyl)phosphines with hexachloroethane or phosgene lead to chloro-phosphines (equation 42)66. It should be noted that treatment of bis(trialky lsilyl)phosphines... [Pg.510]

Clean monochlorination of all possible ring positions in imidazole is most likely to be successful using the lithio precursors, e.g. 1-benzyl-2-lithioimidazole reacts with hexachloroethane to give l-benzyl-2-chloro-imidazole [10, 11] quenching the 2-lithio derivative of 1-tritylimidazole with chlorine, followed by deprotection gives 2-chloroimidazole in 39% yield... [Pg.228]

Carbon-Halogen Bonds. Carbon-halogen bonds may be prepared directly via the lithio intermediate or a second intermediate prepared from the lithio intermediate. For example, reaction of hexachloroethane with 2-lithiodimethylaminomethylferrocene gave the chloro derivative (Reaction 16) (23). However, preparation of other halogen derivatives via lithio intermediates has not been successful. A better and more versatile method for preparing the chloro, bromo, and iodo derivatives involves isolating a boronic acid intermediate as in Reaction 17 (24). [Pg.238]

A key intermediate for the synthesis of several derivatives is 2-lithiotellurophene, obtained by metallation of tellurophene with 2-butyllithium in ethereal solution. Treatment of 2-lithiotellurophene with dimethyl sulfate, -methyl form anilide, acetaldehyde, carbon dioxide, hexachloroethane, hexabromoethane, and dimethyl sulfide gives, respectively, 2-methyltellurophene (10), tellurophene-2-carboxaldehyde (9), l(2-tellurienyl)ethanol (11), 2-tellurophenecarboxylic acid (12), 2-chloro-(13), 2-bromo- (14), and 2-methylthiotellurophene (15). [Pg.144]

The products of the reaction between alkyldiphenylphosphines and hexachloro-ethane in the presence of a tertiary amine are the ylide (88) and the a-chloro-alkylphosphine (89), which are interchangeable, constitutional isomers that interconvert via an intramolecular reversible 1,2-chlorine shift from phosphorus to carbon. Application of the triphenylphosphine-hexachloroethane reagent for the self-condensation polymerization of / -aminobenzoic acid has been studied in detail. Related reactions between dicarboxylic acids and diamines, conducted in the presence of pyridine, involve the cationic phosphorane (90) as a key intermediate. Replacement of hexachloroethane by hexabromoethane or... [Pg.15]
