Preparation of alkyl halidesAlkyl halides are produced by an exchange reaction wherein a halo-hydrocarbon is contacted with a different halo-hydrocarbon in the presence of an organic quaternary salt catalyst.STARKS; CHARLES M.GORDON; RONNIE D....
CONSTITUTION:The objective compound of formula ArX (Ar is aryl; X is halogen), e.g. aryl chloride, is prepared in a short time, by reacting an organic thionitrite or thionitrate of formula R-SNOx ( R is alkyl, cycloakyl, aryl, aralkyl, or heterocyclic group; x is 1-2), e.g. ...
Preparation of acyl halides (I) by the reaction of halides of secondary or tertiary radicals derived from non-aromatic hydrocarbons (II) with carbon monoxide under elevated pressure in the presence of catalytic amounts of a Lewis acid, the catalyst consisting of a mixture of alkylaluminum halides...
The preparation of disulfides mainly rely on oxidative couplings of two sulfur containing compounds. This strategy has many side reactions and other shortcomings. Herein, we describe the reductive nickel-catalyzed cross-electrophile coupling of unactivated alkyl bromides with symmetrical alkyl- and aryl...
alkali metal ions, since alcoholic moieties are also used as media solvating alkali metal ions, e.g., alcoholic potash is used in an elimination reaction of alkyl halides to olefins and in a saponification reaction of esters, in which ethanol dissolves organic substrates and inor- ganic bases...

have reported the synthesis of alkyl-grafted graphene by the reaction of Na-THF-GICs with alkyl halides; they determined that the length of the alkyl chain in the solvent and the concentration of Na affected exfoliation and grafting [21]. In addition, the grafting of molecules or polymers on...
tetraalkylphosphonium halides containing at most 16 carbon atoms, such as the tetra-n-butylammonium or tetra-n-butylphosphonium chlorides or bromides. The salts of tertiary amines may be chosen from among the hydrohalides of trialkylamines containing at most 10 carbon atoms, such as triethylamine...
The following are representive of contemplated alkylating agents: Iodoacetic acid Iodoacetamide Iodoacetate Bromoacetate Iodomethane Bromoacetanilide Alkyl halides, such as ethylbromide, butylchloride Benzylchloride Phenyl chloromethyl ketone Benzyl chloromethyl ketone ...
