摘要：

PARSOL(R) 1789 exists in solution in three tautomeric forms: two cis-enols and a beta-diketone. The enol forms predominate. Irradiation of a very dilute solution of PARSOL(R) 1789 in acetonotrile with a Xenon lamp increases the percentage of beta-diketone to become the predominant form present. This photoisomerisation has been studied by means of H-1 and C-13 NMR.
