Sulfonylative and azidosulfonylative cyclizations by visible-light-photosensitization of sulfonyl azides in THF (2017)
Journal Article
Zhu, S., Pathigoolla, A., Lowe, G., Walsh, D. A., Cooper, M., Lewis, W., & Lam, H. W. (2017). Sulfonylative and azidosulfonylative cyclizations by visible-light-photosensitization of sulfonyl azides in THF. Chemistry - A European Journal, 23(69), doi:10.1002/chem.201704380. ISSN 0947-6539

The generation of sulfonyl radicals from sulfonyl azides using visible light and a photoactive iridium complex in THF is described. This process was used to promote sulfonylative and azidosulfonylative cyclizations of enynes to give several classes o... Read More

Thionated perylene diimides with intense absorbance in the near-IR (2015)
Journal Article
Llewellyn, B. A., Davies, S. E., Pfeiffer, C. R., Cooper, M., Lewis, W., & Champness, N. R. (2015). Thionated perylene diimides with intense absorbance in the near-IR. Chemical Communications, doi:10.1039/C5CC09962E. ISSN 1359-7345

A synthetic strategy involving a combination of tetra-thionation and amine substitution in the bay region of a perylene diimide (PDI) leads to remarkable examples of neutral PDIs with intense absorption maxima in the near infrared. Generation of the... Read More
