Jones oxidation using sodium dichromate

It is also possible to prepare a chromic acid solution by treating sodium dichromate (Na2Cr207) or potassium dichromate (K C Ot) with sulfuric acid. Consequently, sodium14 and potassium15 dichromate can be used, instead of chromium trioxide, in Jones oxidations. 

Interestingly, in Jones oxidation, chromic acid is almost always generated from chromium trioxide while in the rest of the chromic acid oxidations, sodium or potassium dichromate are almost exclusively used. This seems to be the result of an irrational tradition originated since the reagents...
