P. Salehi et al., Solvent-free oxidations of alcohols, oximes, aldehydes and cyclic acetals by pyridinium chlorochromate, SYNTHESIS-S, (15), 2001, pp. 2273-2276
Oxidative transformations of alcohols, oximes and cyclic acetals to carbony
l compounds proceed efficiently by pyridinium chlorochromate (PCC) under so
lvent-free conditions. The oxidation of aromatic and cinnamylic aldehydes t
o carboxylic acids, which does not occur by PCC in solution. is achieved sa
tisfactorily in the absence of solvent.
