PCC with substituted pyridines I was wondering if substituted pyridines can work the way pyridine does in order to oxidize alcohols to aldehydes.
Of course, I'm referring to pyridines without any functional group which can undergo oxidation reactions (eg: I was thinking methylpyridine, or trimethylpyridine, with the nitrogen untouched.)

I guess that the reactivity is the same, but is there any reference to the use of this kind of reagent?
Collidinium chlorochromate and gamma-picolinium chlorochromate are known oxidising agents. e.g. Synth Comm. 31 2001 1253

I see no reason why other methyl pyridines should not also work.
