The electrochemically oxidative cleavage of ligninβ-O-4modelcompounds 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

Efficient Synthesis of Functionalised 4-Hydroxycyclopent-2-en-1-ones by Cyclisation of 1,3-Bis(silyl) Enol Ethers and 1,3-Dicarbonyl Dianions with 1,2-Diketones
of α-keto- or α- formyl acetals by Witting reaction with cyclopropylidenetriphenyl-phosphorane leads to α cyclopropylidene-acetals, easily deacetalized by moist silicagel into the corresponding α-cyclopropylidene-ketone and α-cyclopropylidene-aldehydes. The conversion of the latter to the former is also easily carried out by reaction with Grignardreagents followed by oxidation with active manganese
