Sterically bulky N,N′-disubstituted cyclic thiourea ligand L1 has been demonstrated as an efficient ligand in palladium-catalyzed oxidation of alcohols using molecular oxygen as an oxidant. This new catalyst system has been applied to a wide variety of substrates such as benzylic alcohols, aliphatic secondary alcohols and allylic alcohols, producing the corresponding carbonyl compounds in good to excellent yields.

The invention provides N,N′-disubstituted monothiourea or bis-thiourea-Pd(0) complexes that are useful as catalysts for palladium-catalyzed Heck reaction of aryl iodides and bromides with olefins, and as catalysts for palladium catalyzed Suzuki reactions of organoboric compounds and aryl halides.
Sterically bulky thioureas as air- and moisture-stable ligands for pd-catalyzed heck reactions of aryl halides

We demonstrate that sterically bulky N,N′-disubstituted cyclic thiourea-Pd(0) complexes are air- and moisture-stable and highly active catalysts for palladium-catalyzed Heck reaction of aryl iodides and bromides with olefins (TONs up to 500 000 for the reaction of Phl and methyl acrylate). Even activated aryl chlorides can undergo complete conversion in Bu 4NBr in the presence of 1 mol % Pd catalyst.
