4-Thiophenyl phenyl diphenyl sulfonium hexafluoroantimonate synthesis
- Product Name:4-Thiophenyl phenyl diphenyl sulfonium hexafluoroantimonate
- CAS Number:71449-78-0
- Molecular formula:C24H19F6S2Sb
- Molecular Weight:607.29
Yield:71449-78-0 98%
Reaction Conditions:
with potassium hexafluoroantimonate;sulfuric acid;acetic anhydride in acetonitrile at 45; for 1 h;Product distribution / selectivity;
Steps:
5
The same procedure as in Example 2, except that 5.86 g (21.3 mmol) of potassium hexafluoroantimonate was used instead of potassium hexafluorophosphate, and 5.86 g of acetonitrile was used instead of acetic acid, afforded 11.56 g (yield: 98%, purity: 94%) of slightly yellow solid substance. In this case, 5.7 g of solvent consisting mainly of acetonitrile was recovered, and the wash water was neutralized with 10 g of 40% aqueous caustic soda. [0061] <13>C-NMR analysis and IR analysis indicated that the solid substance obtained contained small amounts of raw materials. [0062] This tar-form substance was treated with 10 ml of ethanol and dried, thus producing 10.4 g of a white powder. The purity was more than 99%.
