Are PCC and Collin's reagent completely identical in their oxidizing action? Is there any advantage (or disadvantages) over the other?


In the Wikipedia article of PCC, it is written that:

PCC offers the advantage of the selective oxidation of alcohols to aldehydes or ketones, whereas many other reagents are less selective.

Further, on the Wikipedia article of Collin's reagent, it is written that:

This complex is both difficult and dangerous to prepare, as it is very hygroscopic and can inflame during preparation. It is typically used in a sixfold excess in order to complete the reaction. Nowadays, PCC or PDC oxidation have largely supplanted Collins oxidation for these reasons.

    $\begingroup$ Okay, so PCC wins in preparation part. $\endgroup$ – Reeshabh Ranjan Dec 8 '16 at 3:37
