Aryl sulfides are ubiquitous structural motifs found in numerous pharmaceutically active compounds and medicinally important natural products.Therefore,a variety of methods for the C-S bond construction to synthesize aryl sulfides have been developed.A typical method is based on inorganic sulfur reagents,in which sulfur powder (S8),which is abundant and smell-free in nature,has been extensively investigated for introducing sulfur atoms into organic molecules.[1]In recent years,the transition metal-catalyzed direct sulfenylation of C-H bond using inorganic sulfur as the sulfur source has attracted considerable interest,since this strategy provides a more atom-economic route to construct the C-S bond by omitting substrate pre-activation.Recently,we and others have developed various approaches for C-H sulfuration using sulfur powder as sulfur source,[2]whereas most of the procedures described above were carried out in organic solvents.From the perspective of green chemistry,water is a desirable reaction medium because of its inexpensive,nontoxic and environmental-friendliness.As our continuing efforts using water as an ideal solvent for the C-H sulfenylation,[3]herein,we disclose a novel and environmentally-friendly protocol for the synthesis of aryl sulfides via C-H bond functionalization of arenes with iodohydrocarbon and sulfur powder under aqueous conditions.
