Secondary nitroalkanes can be converted into ketones by using Y. Identify Y from the following
aqueous HCl
aqueous NaOH
KMnO4
CO
Alkyl cyanides undergo Stephen reduction to produce
aldehyde
secondary amine
primary amine
amide
A.
aldehyde
An alkyl cyanide is dissolved in ether or better in ethyl formate or ethyl acetate, and reduced with SnCl2 and HCl, and then steam distilled. This whole process is called Stephen reaction. In this process alkyl cyanide is reduced to aldehyde.
There is no analogous method for the preparation of ketones.
Reaction of PCl3 and PhMgBr would give
