In ref. 8, B-values were determined by using polymer-bound RB (Sensitox). The insoluble sensitizer did not allow to determine R by extrapolation to zero sensitizer concentration thus leading to too small kr-values (especially in CC14) and, consequently, to a too large dipole moment for the transitio
Singlet oxygen reacts with 1-acetyl-Z-methoxycyclopentene (la) to give the unsaturated hemiperketal 3a. the epoxy-B-diketone% 3a decomposes by an intermolecular oxygen atorn transfer to give -\* Several S-alkoxyenones which are held in the s-trans conformation failed to react with singlet oxygen.
