Abstract: | The excitation yield of the singlet molecular oxygen 1Δ
g
φ(1O2)] in the reaction of the dimethyldioxirane with the chloride ion in benzene, acetone, methylene chloride, and acetonitrile
solutions has been determined. The φ(1O2) value depends on the solvent nature and is in the range 50–84%. Correlation between the value of the singlet oxygen yield
and the Kamlet-Taft parameter (α) characterizing the acidity of the solvent as a hydrogen bond donor has been established:
the higher the α value, the higher the 1O2 yield. |
