Reaction Conditions:
with sodium bromate in water at 80; for 0.583333 h;Ionic liquid;
Steps:
Oxidation of sulfides, tellurides and phosphines; general procedure
General procedure: A mixture of sodium bromate (3.12 mmol), and substrate 1 or 3 or 5(1.04 mmol) in 4 mL of [bmim]HSO4:H2O (3:1, v/v) was placed in a 50 mL round-bottomed flask mounted over a magnetic stirrerand fitted with an air condenser. The contents were heated in an oil-bath maintained at 80 °C for the time specified in Table 2 and 3.The progress of the reaction was monitored by TLC using ethylacetate:petroleum ether (50:50, v/v) as eluent. After completion ofthe reaction, the contents were allowed to cool to room temperature.A saturated solution of sodium thiosulfate (~5 mL) was added into thereaction mixture in order to remove excess unreacted bromine. Themixture was poured into a beaker containing ice cold water (~30 mL)and stirred well. The solid product was filtered under suction pumpand recrystallised. The products were characterised by its m.p., IR andNMR spectra.
