| abstract | 1393517 Unsaturated organotin mercaptides RHONE-POULENC SA 11 April 1973 [12 April 1972 14 March 1973] 17465/73 Heading C2J [Also in Division C3] An unsaturated organotin mercaptide is prepared by (a) reacting, to form an intermediate, x mols. of HS-X-COOH where X is C 1-4 alkylene or phenylene with y 1 mols. of HO-Y-OH or a mixture thereof with at least one of y 2 mols. of HO-Y<SP>1</SP>-OH and y 3 mols. of ROH where Y is a divalent C 1-10 aliphatic hydrocarbyl or C 5-6 cycloaliphatic radical and has at least one of an ethylenic and acetylenic bond and no more than two of each, Y<SP>1</SP> is C 1-10 alkylene or C 5-6 cycloalkylene, R is C 1-8 alkyl or alkenyl, C 5-6 cycloalkyl or cycloalkenyl, or phenyl-(C 1-4 alkyl) and x, y 1 , y 2 and y 3 are subject to the following inequalities and (b) reacting the intermediate with z 1 mols. of R 1 R 2 SnO or R 1 R 2 SnCl 2 , or a mixture of either thereof with z 2 mols. of a stannoic acid monomer or polymer thereof of recurring unit R 1 SnO 1 . 5 or with R 1 SnCl 3 , R 1 Sn(OH)Cl 2 or R 1 Sn(OH) 2 Cl where R 1 and R 2 are C 1-10 alkyl and x, z 1 and z 2 are subject to the following inequalities When any or all of y 2 , y 3 and z 2 are 0, the above inequalities become considerably reduced. The reactions may be effected in a water-immiscible solvent with removal of water by azeotropic distillation. Step (a) may be effected in the presence of an acid catalyst and step (b) in the presence of NH 3 or an amine as HCl acceptor. In the examples 2-butene-1,4-diol Πisobutyl alcohol, 2-butyne-1,4-diol, thioglycollic acid, #- mercaptopropionic acid and di-(n-butyl)- and di-(n-octyl) tin oxides are used as reactants and the products may typically, as in Example 1, consist of groups of formulae and also, as in Example 4, of formula The compounds are useful as stabilizers for halogenated vinyl resins. |
