Samanta, Partha Kumar published the artcileCopper(0) nanoparticles immobilized on SBA-15: a versatile recyclable heterogeneous catalyst for solvent and ligand free C-S coupling reaction from diverse substrates, Recommanded Product: 2-Phenylethanethiol, the publication is Microporous and Mesoporous Materials (2021), 111198, database is CAplus.
A SBA-15 supported copper(0) nanoparticles based catalyst (Cu(0)MS) has been prepared using wet impregnation method. The catalyst was thoroughly characterized by several techniques including powder X-ray diffraction, nitrogen adsorption-desorption, field emission SEM-energy dispersive X-ray, transmission electron microscopy, high angle annular dark field scanning transmission electron microscopy and inductively coupled plasma-optical emission spectrometry. This mesoporous silica supported copper(0) nanoparticles had been exploited as a catalyst for ligand-free and solvent-free C-S cross-coupling reactions. Sym./unsym. aryl/alkyl sulfides R1SR2 (R1 = Ph, 2-MeOC6H4, PhCH2, PhCH:CH, 2-thienyl, etc.; R2 = Ph, n-octyl, PhCH2CH2, 2-pyridyl, etc.) had been synthesized by the S-arylation of aromatic, heteroaromatic and aliphatic thiols R2SH with aryl, heteroaryl or vinyl halides R1X (X = I, Br). Aryl chlorides also responded the reaction very well to produce aryl sulfides. The applicability of the current protocol had also been explored for the synthesis of the starting materials of different C-S bond containing pharmaceuticals. In addition, the present catalytic system was also suitable for the synthesis of a variety of sym. diaryl sulfides from aryl halides using thiourea as a sulfur source. Furthermore, it was also found that the Cu(0)MS catalyst could be reused five times without substantial loss in activity.
