[摘要]:Trihexyl(tetradecyl)phosphonium hexafluorophosphate, a phosphonium salt ionic liq. (PSIL) is a particularly effective general reaction media for the Pd-catalyzed carbonylation reaction of iodoarenes and thiols to form thioesters. Recycling of the ionic liq. contg. active Pd-catalyst was also demonstrated. |
