Rose Bengal-induced photofragmentation: Singlet oxygen revisited

Article abstract of DOI:10.1016/0040-4039(91)80519-C

The Rose Bengal-induced photofragmentation of β-amino alcohols has been previously reported to proceed through a mechanism involving singlet oxygen sensitization, followed by attack of singlet oxygen and superoxide on the β-amino alcohol. An alternative mechanism involving electron transfer from the amine to the excited state Rose Bengal is supported by new evidence.
