Yield:-
Reaction Conditions:
in N,N-dimethyl-formamide at 20; for 72 h;
Steps:
4.2
1,14-dibramo-3,6,9,12-tetraoxatetradecane (3.35 g, 9.2 mmol) and sodium methanethiosulfonate (2.48 g, 18.5 mmol) were dissolved in dry DMF (40 mL) and stirred at room temperature for 3 days. The solvent was evaporated. The residue was purified by column chromatography on SiO2. Elution with ethyl acetate/hexane (9:1) afforded, after evaporation, 1-(14-bromo-3,6,9,12-tetraoxatetradecyl) methanethiosulfonate (0.85 g) as a pale yellow oil and tetraoxatetradecane-1,14-diyl-bis-methanethiosulfonate (useful as a cross linker) as a slightly yellow colored oil (1.64 g).
