Carbon- carbon multiple bond compounds in the application of chemistry, organic chemistry , and other related disciplines plays an important role . Multiple bond compounds containing functional groups , especially aromatic modified acetylenic compounds having π electrons and because of the nature of triple bond of carbon-rich structure, not only important in organic synthesis building blocks, and the functional molecules constructed by the fluorescent material , electroluminescent materials, carbon-rich materials and liquid crystal materials and other fields has good application prospects. Given the important role of re- bond compounds , synthetic organic compounds synthesis of such workers has been a lot of work , various synthetic methods continue to emerge. In this thesis, extensive literature research and the laboratory in the past with pot synthesis asymmetric Arylethynylsilanes sulfide based on the results , continue to use the lab 's pot synthesis advantage proposed synthetic symmetrical two Arylethynylsilanes sulfide idea . When acetylene sulfide synthesis designed to aromatic ketones as raw material, through a brominated aromatic ketones , nucleophilic sulfur compounds are used, one-pot process of elimination , the final synthesized a series of two Arylethynylsilanes sulfide compounds. Through pot synthesis of diaryl sulfide with acetylene raw materials readily available, easy synthesis , high yield advantages. This thesis includes the following: In the first chapter , the main features introduced pot , alkynyl sulfide compounds synthesis and synthetic developments and applications in synthesis . Finally established this thesis research topics and research , to find the significance of this research topic . The second chapter describes the synthesis of raw materials . First introduced the acylation reaction , diazotization , bromination reaction , the reaction mechanism and into ether synthesis . Brominated products of the aromatic ketones and aromatic sulfide spectra analysis , describes the synthesis of raw materials , and the results are discussed synthesis . In the paper 's final chapter describes the synthesis of target compounds and the possible reaction mechanism of the structural characterization of the target compounds , and the synthesis of the target compound and gave specific instructions . This intermediate and target compounds of all the structures were by 1HNMR, 13C NMR, MS, IR combined measurement confirmed.
