The electrochemically oxidative cleavage of lignin β-O-4 model compounds mediated by iodide ion has been studied. The results indicate that electrolytic conditions play a predominant role in determining the distribution of cleavage products. The preparative-scale electrolysis proceeds in a simple undivided cell, employing a catalytic amount of NaI as the redox mediator and supporting electrolyte in methanol. Under these conditions, the Cβ[sbnd]O bond is selectively cleaved with 2,2-dimethoxy-2-arylacetaldehyde being the main product. In some cases, the reaction gives a good yield of cleavaged products. The results further demonstrate that the indirect electrolysis mediated by halide is a versatile approach for chemical transformation.

The thermolysis of 5-acyltriazolines 1, 2, 3 (X=COR', Y=CO2Me) was studied.Instead of the expected aziridines, enamides 5 to 8 were obtained by an unusual acyl migration.It has been shown that the reaction is intramolecular and proceeds via a 1,2 followed
