摘要

Magnesium-promoted reductive coupling of chlorotrialkylsilanes and tropone or tropone acetal in DMF, followed by oxidation with 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone in benzene gives 2-trialkylsilyltropones as the main product, and the reductive coupling of tropone with acid anhydrides under similar reaction conditions yields benzene derivatives after ring contraction.
