在可见光照射下，联吡啶钌（[Ru（bpy）（3）]（2+）：TB（II））催化烯胺和醛与2，2，6，6-四甲基哌啶基-1-氧（克里思）的氧化偶联反应，得到α-氧胺化羰基化合物。可见光照射对于产生作为氧化剂的 *TB（II）的三重激发态是必不可少的。这是一种基于光活化TB介导的单电子转移的自由基偶联新方法。
Tris(bipyridyl)ruthenium(II) ([Ru(bpy)(3)](2+) : TB(II)) catalyzes oxidative coupling of enamines and aldehydes with 2,2,6,6-tetramethylpiperidinyl-1-oxy (TEMPO) under irradiation of visible light to afford alpha-oxyaminated carbonyl compounds. The visible light irradiation is essential to generate the triplet excited state of *TB(II) which acts as an oxidizing agent. This is a new procedure for radical coupling based on single electron transfer mediated by photoactivated TB.
