79% | In toluene; for 10h;Dean-Stark; Reflux; | The ligand acid, HL (0.98 g, 5 mmol) and <strong>[870-08-6]di-n-octyltin(IV)oxide</strong> (0.90 g, 2.5 mmol), weresuspended in dry toluene (100 mL) in a single necked round bottom flask (250 mL)equipped with a Dean-Stark apparatus. The mixture was refluxed for 10 h and waterformed during the condensation reaction was removed at regular intervals. A clearsolution thus obtained was cooled to room temperature and the solvent was removedunder reduced pressure. The solid obtained was recrystallized from chloroform andn-hexane (4:1) mixture, Yield: 79%. M.p. gel. Anal. Calcd (%) for C36H50Cl2O4Sn: C,58.70; H, 6.79. Found (%): C, 58.68; H, 6.80.
