| abstract | 1,172,239. Organotin compounds. STAUFFER CHEMICAL CO. 23 Dec., 1966 [27 Dec., 1965], No. 57681/66. Heading C2J. [Also in Division C3] Novel organotin compounds have the formula wherein R<SP>11</SP> and R are selected from a C 1-12 aliphatic group, an alicyclic group, aromatic group and the corresponding halo- and cyanosubstituted groups, R<SP>1</SP> is hydrogen or one of the above groups, and n is 1, 2 or 3. These compounds may be used to prepare mixed tin salts, wherein n is 2 and one of the remaining valence bonds is satisfied by a halogen atom, by reaction with R<SP>11</SP> 2 SnX 2 (R<SP>11</SP> is as above and X is halogen). In the examples the following organotin compounds are prepared (1) triacetoximo butyl tin by reaction of the sodium salt of acetoxime with butyl tin trichloride, (2) diacetoximodibutyltin by reaction of (a) the sodium salt of acetoxime with dibutyl tin dichloride, (b) acetone oxime with dibutyltin dichloride, (c) acetoxime with dibutyltinoxide, (3) acetoximotributyltin by reaction of (a) the sodium salt of acetoxime with tributyltin chloride or (b) tributyltinoxide with acetoxime, and (3) dibenzaldoximedibutyltin by reaction of benzaldoxime with dibutyltin oxide. In a further example, triacetoximo butyltin and dibutyltin dichloride are reacted together to give a mixed salt of acetoxime-dibutyl tin chloride. The organotin compounds may be used as catalysts in the curing of silicone rubbers and in the production of flexible polyurethane foams (see Division C3). |
