摘要

Abstract An economical and effective protocol for large scale synthesis of the 2-phenyl-1, 8adihydroazulene-1, 1-dicarbonitrile (DHA) photoswitch has been developed. This compound is ring-opened by light to a vinylheptafulvene (VHF), which is thermally closed back to DHA. This compound serves as an important starting material for dihydroazulene photoswitches incorporating a substituent in the seven-membered ring and as a reference ...
