摘要：

Synthesis of 2 and 4-aryl cyclohexenones and of hexahydrodibenzofuran derivatives is described. In anhydrous hydrogen fluoride at 0-degrees-C, 4-hydroxy-4 methylcyclohex-2 en-1 one 2 reacted to yield ketone 7 (43%). Reaction of ketone 2 with parabromophenol 3b in HF gave ketone 6 (40%) at - 20-degrees-C and ketone 6 (35%) and 7 (13%) at 0-degrees-C. Under similar conditions ketone 2 reacted with phenol 3a to yield 2 and 4 arylated ketones 4a (4%), 5 (a+b) (25%) and 9a (5%).
