The cyclization of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with halo-substituted enones afforded 3-difluorochloromethyl-, 3-difluorobromomethyl- , 3-dichloromethyl-, and 3-trichloromethylphenols with very good regioselectivity. The hydrolysis of the dichloromethyl group gave functionalized 3-formylphenols, which are not readily available by other methods. Thieme Stuttgart.

Triethylamine catalyzed rearrangement of the substituted bicyclic cycloheptatriene endoperoxides 9, 10, 12, 13, 20, 21, 22 and 30 underwent different reaction modes and resulted in the formation of ring contraction products in the case of 9, 10, 12 and 13. However, 20, 21, and 30 provided rearranged diketones 23, 24 and 32 almost in quantitative yield. The mechanism of these reactions was discussed.
