The REACTION MISCTUR IS HEATED TO 52 C. A solution of 5. 68 G (83 MMOL) of 50% aqueous hydrogen peroxide is added dropwise to the reaction mixture over 2. 5 hours while the reaction temperature is brought to and maintained at reflux (62 C). After the peroxide is added, the reaction mixture is stirred at reflux for 1.75 hours, and then allowed to cool slowly to 33 C. Peroxide is decomposed by the addition of aqueous sodium sulfite solution. The reaction mixture is diluted with ethyl acetate, and the organic layer is washed with water and then concentrated. Purification by flash chromatography with 20: 1 heptane-ethyl acetate affords 4.11 g (59% yield) of the title compound, a colorless liquid. Structure is verified by NMR analysis. |

In benzene;Reflux; | Although the synthesis of[CLPOT-(4-X-TEMPO)] ICs themselves has been reported inour previous work,19 typical methods are described in moredetail in this paper. For example, [(CLPOT)2-(TEMPOL)x] (4)was prepared by pouring 5.8 103 mol of TEMPOL in 1mLof ethanol into 15mL of a boiling 6.0 103 mol L1 CLPOTethanol solution. 3 and [(CLPOT)2-(TEMPONE)x] (5) werealso prepared with a similar method. However, [(CLPOT)2-(MeO-TEMPO)x] (6) was prepared by pouring 1.1 102 molof MeO-TEMPO in 1mL of benzene into 4mL of a boiling6.0 102 mol L1 CLPOT benzene solution. In the synthesisof 6, if the amount of MeO-TEMPO was similar to the synthesisof 35(ca. 6 103 mol), the inclusion amount of MeOTEMPOin the CLPOT nanochannels was small (for instance,[(CLPOT)2-(MeO-TEMPO)0.41]19). These products were obtainedas light-orange powder after cooling the solution to roomtemperature. The synthesis process of the [(TPP)2-(TEMPO)1.0]was simplified by cooling at room temperature after pouring1mL of 6.0 103 mol L1 TPP mesitylene solution at atemperature of 383K into 5.8 103 mol of TEMPO in 1mL ofmesitylene.13 |
