Golden solution: A neutral solution of AuBr3, containing [AuBr2(OH)2]− in equilibrium with [AuBr3(OH)]− and [AuBr4]−, promotes the chemoselective hydrolysis of robust oximes into carbonyl compounds without racemization (see scheme). The food additive diacetyl acts as a NH2OH‐trapping agent, thus avoiding the formation of gold nanoparticles and allows the reaction to run catalytically.
金色溶液:AuBr的中性溶液3,将含有[AuBr 2(OH)2 ] -处于平衡[AuBr 3(OH)] -和[AuBr 4 ] - ,促进健壮肟的化学选择性水解成无外消旋作用的羰基化合物(请参阅方案)。食品添加剂二乙酰可作为NH 2 OH捕集剂,从而避免了金纳米颗粒的形成,并使反应催化进行。
