| abstract | An alkyl, particularly dialkyl, tin ester is prepared by reacting tin, or an alloy thereof, with an alkylating ester in the presence of an alkyl bromide and/or iodine, e.g. 0.05-0.4 mols per mol alkylating ester. An alkylating ester is defined as an alkyl ester of an oxy-acid that is capable of reacting with stannic bromide or icdide to produce the corresponding alkyl halide, for example an alkyl sulphate, sulphonate, sulphite, phosphate or phosphite. The alkyl groups in the ester may have 1-20 carbon atoms, may have inert substituents, e.g. fluoro-, cyano-, ether or thio-ether groups, and they are preferably the same as the alkyl groups in the alkyl halide. Suitable esters are butyl, amyl, hexyl, heptyl and octyl esters, particularly tri-n-butyl and tri-n-octyl phosphates. Reaction may take place at 80-300 DEG C. in presence of one or more of an organic base, e.g. pyridine, a non-oxidizing acid, e.g. phosphoric or p-toluene sulphonic acid, metals, which may be alloyed with the tin, such as copper, silver, magnesium or aluminium, and/or salts of these metals. Optionally a diluent, e.g. halogenated hydrocarbons or high boiling ethers may be used, and in addition a minor proportion of an alcohol, preferably that corresponding to the alkyl group in the ester, may be present. The alkyl tin ester may be isolated by, e.g. filtration, extraction or distillation, or may be hydrolyzed in situ to the alkyl tin oxide, alkyl stannoic acid or salt thereof. |
