We developed novel photobase generators (PBGs) that generate radicals and aliphatic amines simultaneously. We demonstrated that the PBGs induced radical polymerization and hydrolytic polycondensation. A film of poly[(methacryloxypropyl) silsesquioxane] (MA-PS) was cured in the presence of a PBG upon UV-light irradiation at 254 nm. This result showed that radical polymerization of methacryloyl groups of MA-PS with the photogenerated radicals and the crosslinking reactions based on the base-catalyzed condensation reactions of alkoxysilyl units of MA-PS proceeded. Furthermore, pencil hardness showed HB at 1.0 J cm2 and 4H at 21.6 J cm2 without heat treatment.

Ketyl radicals, formed by chemoselective Ti(III) reduction of α,β-dicarbonyl compounds, add to the carbonyl carbon of aldehydes under mild conditions to afford α,β-dihydroxy ketones in good to excellent yields.Simple diastereoselectivity strongly depends on the bulk of groups bonded to both the ketyl radical and the aldehydic function.The relative configuration of two the keto diols was established by single-crystal X-ray diffractometry.
