The synthesis of a,S-epoq sulfoxides (1) and sulfones (2,3) has been described recently. This communication reports the thermal and acid catalyzed rearrangements of a,S-epoxy sulfolddes Ia and Ib and of the corresponding a,@epoxy sulfones, IIa and IIb, as examples of what appears to be a general me
The nickel-catalyzed isomerization of geraniol and prenol in roacetic acid combination. Catalyst deactivation occurs in the course of the reaction owing to coordination of the formed homogeneous and two-phase systems has been investigated. The best results in terms of activity and selectivity have b
