Benzotriazoles allylic alcohol oxidation

Oxidation of allylic alcohols.1 Allylic alcohols are oxidized to the corresponding enones in 80-95% yield by PCC complexed with benzotriazole (CH2C12, 23°). [Pg.262]

Along with reactions without the participation of the radical centre, ARs react as typical radicals. At elevated temperatures, they abstract hydrogen atoms, chlorine, bromine and other elements. There are examples of sufficiently reactive ARs in H-atom abstraction at standard temperatures. The benzotriazole-N-oxyl (BTNO) generated by the oxidation of 1-hydroxybenzotriazole (HBT) with a Ce" salt in acetonitrile spontaneously decays with a first-order rate constant of 6.3 x 10" s" at room temperature [31]. The decay of this aminoxyl is strongly accelerated in the presence of H-donor substrates such as alkylarenes, benzyl and allyl alcohols ... [Pg.23]
