report a simple photoinduced and catalyst-free C–H/C–H (hetero)arylation cross-coupling through aryl thianthrenium salts, which are formed site-selectively by direct C–H functionalization. The key to this approach is the UV-light, which can disrupt the C–S bond to form thianthrene radical cations and aryl radicals.

Pd[0] catalysed coupling between organyl bromides and either 2-lithofuran or 2-furylzinc chloride are described. Arylation by a wide variety of aromatic bromides can be carried out in high yields and on a large scale. Benzylation and cinnamylation are also successful.

conditions, besides the normal functional group tolerance known for palladium-catalyzed reactions, an interesting selectivity was observed with functional groups that are known to react either in palladium-catalyzed reactions or reactions catalyzed by other transition-metals. Thus aryl halides, terminal alkynes, 1,6-enynes, and alpha-allenic alcohols were tolerated. In the latter example the selective reaction
