Sulfonium ylide are important reagents in organic chemistry, this being especially true in the synthesis of naturally occurring products with important biological and pharmacological activities [1]. The synthesis of complexes derived from ylides and Ag(I) began in 1975 by Yamamoto et al. [2]. Other types of ylide complexes of silver(I) have been reported [3,4]. In 2013, Sabounchei et al. reported the crystal structures of Ag(I) complexes of sulfoniumylides [5]. It is well known that silver ions and silver-based compounds are highly toxic to microorganisms. For this reason, there is an urgent need to develop novel antimicrobial agents with difficult mechanisms of action aimed ata better understanding of the antimicrobial resistance. We report the synthesis of stable silver(I) complexes, which are belongs to carbonyl stabilized sulfur ylides. The reaction of sulfoniumylide (Me)2SCHC(O)C6H4R (R=m-OMe) with Ag(I) in dry dichloromethane leads to the formation of C-coordinated mononuclear complexes of the type Ag(NO3) and Ag(OTF).. Characterization of the obtained compounds was also performed by elemental analysis, IR, MS, 1H and 13C NMR that indicated a 2:1 stoichiometry between the silver(I) nitrate and ylide m-Ome. Characterization of the obtained compounds was also performed by elemental analysis, IR, MS, 1H and 13C NMR that indicated a 1:2 stoichiometry between the silver(I) nitrate and ylide m-OMe (Fig. 1).
