%X Oxidation of 10-methyl-9-anthraldehyde with hydrogen peroxide in acetic acid in the presence of sulfuric acid gives 9-formyloxy-10-methylanthracene which dimerizes in solution upon exposure to light. The head-to-tail structure of the 4&#960;+4&#960; photodimer was established by a single-crystal X-ray diffraction study. In the crystalline state, the molecular structure is centrosymmetric, and the length of the photochemically formed bonds 1.646(4)&#506;. Crystals are monoclinic, P21/c, a 7.980(5), b 16.143(7), c 9.571(3)&#506;, &#946; 114.38(3)&#176;, Z=2 dimers; R was 0.041 for 1362 'observed' diffractometer reflections.
