K. Nakatani et al., HIGHLY EFFICIENT PHOTOCHEMICAL GENERATION OF O-QUINONE METHIDE FROM MANNICH-BASES OF PHENOL DERIVATIVES, Tetrahedron letters, 38(28), 1997, pp. 5005-5008
o-Quinone methide was efficiently produced by photoirradiation of phen
olic Mannich bases in aqueous acetonitrile with low energy UV light. T
he photoreaction proceeds most effectively at neutral pH in aqueous so
