Tetrabutylammonium permanganate preparation

Homogeneous oxidations are accomplished with tetrabutylammonium permanganate prepared by treating an aqueous solution of potassium permanganate with tetrabutylammonium bromide and isolating the crystalline precipitate [845, 599]. Tetrabutylammonium permanganate is soluble in dichloromethane, chloroform, acetone, and pyridine and sparingly soluble in benzene ( purple benzene ). [Pg.129]

On the other hand, potassium permanganate is frequently used to prepare carboxylic acids from both aliphatic [86S] and aromatic aldehydes [555]. High yields of carboxylic acids are also obtained by oxidation with tetrabutylammonium permanganate [599] or benzyltriethylammonium permanganate [903] (equation 350). Recently, doubts about the safety of work with quaternary ammonium permanganates have been raised [967]. [Pg.176]
