Acid catalyzed condensation reaction reactions of 1-oxaspirodeca-6,9-diene-2,8-dione (1) (quinolactone) with phenols and phenol-ethers 2a-i to yield biphenyls 3a-i and 4a-f were found to proceed by an elimination-addition mechanism.Keywords-- condensation; acid catalysis; biphenyl; quinol-lactone; phenol; phenol-ether; elimination-addition mechanism
