✦ Synopsis


The photolysis of cu-pyrones in the solution phase has received considerable attention.

In this communication, we would like to present some observations regarding the solid state photolysis of o-pyrones in contrast to their solution photolysis.

In addition, we would like to report an unusual rearrangement of one of the photo-products.

The photolysis of a saturated benzene solution of 4,6-dimethyl-o-pyrone yields syn and anti dimers resulting from 4 + 4 cycle-addition and another dimer from 2 + 2 addition.
