The photoreduction of triplet benzophenone by 14 tertiary amines was investigated. The ketyl radical yields do not correlate with the quenching rate constants, nor with the electron donor propensity of the amines. Individual structural features of the amines seem to determine the photoreduction yields.

Organic perylene diimide-based compounds are provided. Methods of producing the organic compounds is also provided as well as methods of their use including, among other things, their use as organic semiconductor materials.
The present invention provides processes for preparing normorphinans from N-substituted morphinans. In particular, the invention provides methods for removing the N-substituent from the N-substituted morphinan to from a normorphinan carbamate, and then removing the carbamate functionality from the normorphinan carbamate to form the normorphinan.
