Trityl ethers of carbohydrates, B. Helferich, Adv. Carbohydr. Chem., 3 (1948). Applications in the carbohydrate field of reductive desulfurization by Raney nickel, H. G. Fletcher, Jr. and N. K. Richtmyer, Adv. Carbohydr. Chem., 5 (1950). 

Two techniques, electrochemical reduction (section IIl-C) and Clem-mensen reduction (section ITI-D), have previously been recommended for the direct reduction of isolated ketones to hydrocarbons. Since the applicability of these methods is limited to compounds which can withstand strongly acidic reaction conditions or to cases where isotope scrambling is not a problem, it is desirable to provide milder alternative procedures. Two of the methods discussed in this section, desulfurization of mercaptal derivatives with deuterated Raney nickel (section IV-A) and metal deuteride reduction of tosylhydrazone derivatives (section IV-B), permit the replacement of a carbonyl oxygen by deuterium under neutral or alkaline conditions.
