The Wolff-Kishner reduction was discovered independently by N. Kishner[REF] in 1911 and L. Wolff in 1912 [REF].
The method developed by Kishner has the advantage of avoiding the requirement of a sealed tube, but early variations of Wolff's procedure involved the use of high-boiling solvents such as triethylene glycol to alleviate this necessity [REF].
