Mechanistic Photochemistry of 1-Adamantylacetone.

摘要

Irradiation of 1-adamantylacetone (1) results in essentially a quantitative yield of two cyclobutanols, 2 and 3. Quantum yields for the formation of 2 and 3 from the S1 and T1 states of 1 in benzene and methanol are reported. Formation of cyclobutanols from the excited triplet state of 1 is much more efficient in methanol than in benzene.
