Pincer-type diphenyl sulfide compound, and preparation method and use thereof

Abstract

A structurally symmetrical diphenyl sulfide compound, and a preparation method and use thereof are provided. The structurally symmetrical (pincer-type) diphenyl sulfide compound (ES/EO) is used as an exemplified extractant. Principal active sites of pincer-type extractants are positioned on both flanks in a framework of the diphenyl sulfide compound, enabling formation of dual coordination architectures with the Au(III) and the Pd(II) in precious metals (PMs), while a central sulfur atom exhibits extraction capability specific to Pd.
