Potassium thiocyanate acts as an efficient sulfur surrogate in C-S cross-coupling reactions mediated by recyclable copperoxidenanoparticles under ligand free conditions. This protocol avoids foul smelling thiols, for the synthesis of a variety of symmetrical diaryl sulfides, via the cross-coupling of different aryl halides with potassium thiocyanate, affording corresponding products in moderate to
and highly efficient protocol for the synthesis of symmetrical aryl sulfides was developed by the cross-coupling of aromatic halides with inexpensive and commercially available thiourea which was used as an effective sulfur surrogate. The present cross-coupling protocol of thiourea, via cascade reaction with various substituted arylhalides, producing desired aryl sulfides, has an added advantage of
transition metal catalysis, photoinduced catalysis has emerged as a versatile and sustainable way to achieve carbon–heteroatom bond formation. This work discloses a visible-light-induced reaction for the formation of a C–S bond from aryl halides and inorganic sulfuration agents via electron donor–acceptor (EDA) complex photocatalysis. Divergent formations of organic sulfide and disulfide have been demonstrated
