Treatment of an aldose diethyl thioacetal with a limited amount of aged Raney nickel catalyst resulted in the reductive cleavage of one thioethyl group. 1-Deoxy-1-S-ethyl derivatives of D-galactitol, L-arabitol, L-rhamnitol, and D-glucitol have thus been synthesized and their structures proved. 1-Deoxy-1-S-ethyl-L-galactitol has been prepared by the borohydride reduction of 6-deoxy-6-S-ethyl-D-galactose.

Detosylations of derivatives of methyl 12-toluene-p- sulphonyloxypodocarpa-8,11,13-trien-19-oate have been investigated using a modified W-7 Raney nickel catalyst. The final steps in a conversion of podocarpic acid (1) into (+)-19-hydroxypodocarp-8(14)-en- 13-one (21), a useful intermediate for synthesis, have been effected.

A hydrophobic porous hydrogen anode was prepared whose electrochemical parameters are comparable with anodes containing a platinum catalyst. For its successful preparation, oxidation of the Raney nickel catalyst with air oxygen or with fluorine from Teflon must be prevented. The electrodes of a geometric surface area up to 450 cm2 were tested in cells and modules filled with 7M-KOH.
