<div>While carbon-heteroatom cross coupling reactions have been extensively studied, many methods are specific and</div><div>limited to a set of substrates or functional groups. Reported here is a method that allows for C-O, C-N and C-S cross coupling reactions under one general methodology. We propose that an energy transfer pathway, in which an iridium photosensitizer produces an excited nickel (II) complex, is responsible for the key reductive elimination step that couples aryl halides to 1° and 2° alcohols, anilines, thiophenols, carbamates and sulfonamides.</div>

Energy Transfer Pathway

Transfer of excitation from cadmium to sodium atoms was investigated in anheat pipe oven illuminated by a pulsed laser tuned on the intercombinationtransition of cadmium. A rich emission spectrum with cadmium as well assodium lines was observed. Intramultiplet mixing distributes the initialexcited level population 5p3P1 to the nearby fine structurelevels 5p3P0,2 of the same multiplet. We have experimentalevidence that the energy transfer pathway is from Cd (5p3PJ) to Na(4p2PJ) which is collisionally rapidly converted toNa(3d2DJ), from which the strongest emission was observed.PACS No.: 34.90+q
