Nitromethane water

The posphonium iodides are rather insoluble in all common organic solvents except nitromethane. Water hydrolyzes the compounds to trialkylphosphane oxides2. [Pg.198]

The tetrabromoaurate ion catalyzes the oxidation of organic sulfides by nitric acid in two-phase solvents such as nitromethane/water. This anion is about ten times more reactive than [AuC ]", yet does not lead to sulfone production. It is thus quite suitable for oxidizing hindered sulfides. The mechanism appears to resemble that with [AuCl4]", involving replacement of Br by R2S to give [AuBr3(SR2)], which oxidizes another SR2 by atom transfer. Although Br itself can catalyze the reactions, it does not compete effectively with the Au(III) system. [Pg.92]
