The invention discloses a kind of diaryl sulfide class compound and its synthetic methods, using high salt compounded of iodine as reaction raw materials, under the action of odorless sulfiding reagent, alkali, metallic catalyst and ligand, under the conditions of 60~100 DEG C, is reacted 3~12 hours in dimethyl sulfoxide (DMSO) and obtain all kinds of diaryl sulfide class compounds.The method that the present invention introduces sulphur by the later stage, avoid sulphur in reaction early period to metallic catalyst poison and incompatibility with oxidant；Moreover, inorganic sulphur source is nontoxic, odorless；In addition, two aryl make full use of in high salt compounded of iodine, the Atom economy of the method for the present invention is fully shown.The diaryl sulfide class compound being prepared by the method for the invention can further apply the synthesis of photoelectric material BTBT and anti-inflammation drugs Zaltoprofen (Zaltoprofen). |
