which benefit from small nanocrystalline size (10–30 nm, according to the XRD and TEM data) in combination with the coexistence of magnetic nanoparticles, a metal–organicframework, and cobalt species, were found to be an excellent environment catalyst to promote the C–N and C–S cross coupling reactions. A wide range of functional substrates including electron-withdrawing and electron-donating aryl halides

Beta substitutedthiols and various derivatives containing the HX–C–C–SH motif oligomerise in water, preferably in the presence of a carbonate salt. The reaction yields oligomers consisting of one thiol end group, a thiaethylene backbone and an additional terminal group corresponding to the starting material used. Mechanistic studies, as well as the scope of substrates and products of these new promising

Disclosed is a method for the β-C—H H functionalization of carbonyl compounds that is both selective and broadly applicable. The methods provide direct β-arylation of carbonyl compound with a diverse array of aryl or heteroaryl halides, aryl or heteroryl tosylate, aryl or heteroaryl triflates, or diaryliodonium salts, by palladium catalysis in the presence of a ligand and promoter.
