Summary

  1. 1.

    The cycloalkenylation of phenol with 1,3-cyclohexadiene in the presence of a mixture of phosphoric and sulfuric acids was studied.

  2. 2.

    The reaction products were o-(cyclohexen-2-yl)phenol in 39% yield and p-(cyclohexen-2-yl)phenol in 28% of theoretical yield.

  3. 3.

    Isomerization of o- and p-(cyclohexen-2-yl)phenols in the presence of potassium hydroxide gave the corresponding (cyclohexen-1-yl)phenols.

  4. 4.

    The cyclization product of o-(cyclohexen-2-yl)phenol was 2,3-cyclohexano-2,3-dihydrobenzofuran.
