Conclusions
-
1.
Diisobutyl disulfide at a temperature of 210–220°, in the presence of catalytic amounts of KOH or Na2S2, is almost quantitatively cleaved with the formation of isobutanethiol (80–97%), hydrogen sulfide and isobutylene.
-
2.
In the presence of catalytic amounts of the base, cleavage practically does not occur at a temperature of 170–180° and lower.
