, p. 4742 - 4749 (2007/10/02)
In an aqueous alkaline solution, the photoisomerization of norbornadiene derivatives 1 to quadricyclane derivatives 2 was investigated.Upon irradiation with sunlight, 1a-g isomerized quantitatively to 2a-g even in the presence of air, although the reactio

Use of copper(I)-nitrogen ligand catalysts such as Ph3PCuCl*bpy (3), Ph3PCuCl*phen (4), Ph3PCuCl*phtha (5), and Ph3PCuBr*py (6) enables the photochemical isomerization of norbornadiene to quadricyclane to be performed at a longer wavelength than 350 nm, a
HIGHLY EFFICIENT VALENCE ISOMERIZATION BETWEEN NORBORNADIENE AND QUADRICYCLANE DERIVATIVES UNDER SUNLIGHT

, p. 839 - 842 (2007/10/02)
3-Phenylcarbamoyl-2,5-norbornadiene-2-carboxylic acid (1b) undergoes a facile and quantitative isomerization into the corresponding quadricyclane derivative (2b) under sunlight.The back isomerization of 2b to 1b proceeds quantitatively by the use of catal
