Abstract
:
The deep yellow fulgide 6 and its dicyanomethylene 9 underwent a conrotatory ring closure to the colored forms 7 and 10 respectively. The latter compounds revert back to the original forms on exposure to white light. The replacement of the carbonyl group by the dicyanomethylene group resulted in a large bathochromic shift of both the colored and uncolored forms 9 and 10 respectively.
