A palladium-catalyzed four-component carbonylative cyclization reaction for the expeditious construction of trifluoromethyl-containing trisubstituted imidazoles has been achieved. With readily accessible trifluoroacetimidoyl chlorides, propargyl amines, a

This report describes the Na2PtCl4 catalyzed C-H arylation of arene substrates with diaryliodonium salts. The site selectivity of these reactions is predominantly controlled by steric factors. Remarkably, Na2PtCl4-catalyzed naphthalene arylation proceeds with opposite site selectivity compared to that obtained with Na2PdCl 4 as the catalyst. Preliminary mechanistic studies provide evidence for a PtII/PtIV catalytic cycle involving rate-limiting C-C bond-forming reductive elimination.
One-pot synthesis of diaryliodonium salts using toluenesulfonic acid: A fast entry to electron-rich diaryliodonium tosylates and triflates

A direct synthesis of symmetric and unsymmetric electron-rich diaryliodonium salts is described. The use of MCPBA and toluenesulfonic acid delivers diaryliodonium tosylates in high yields. An in situ anion exchange has also been developed, giving access to the corresponding triflate salts. Georg Thieme Verlag Stuttgart.
