Acceptor-substituted cycloalkenones 1 undergo an iron(III)catalyzed vinylogous Michael reactiona sequence of enone-dienol tautomerism, [4+2]-cycloaddition, and retro-aldol reactionwith quinone derivatives 3. A variety of products is obtained ranging from meta-terphenyl precursors 5 to

In the preceeding communication1 we reported that aryllead(IV) tricarboxylates react readily at room temperature with trifluoroacetic acid (TFA) to give high-yields of aryl trifluoroacetates, and we proposed that aryl cations2'3'4 are intermediates in these reactions.
Diazo Compounds
A practical and novel ionic liquid promoted organocatalytic selective diazo-transfer process for the synthesis of highly substituted diazo-compounds in high yields is reported. The ionic liquid can be reused without affecting the reaction rates or yields over five runs.
