Transition Metal Complexes of α-keto Stabilized Sulfonium Ylides: Linear in Contrast to Bridging Structure in Silver(I) Complexes

Furthermore, from the reaction of sulfonium ylides ( Y 1 ), (Me) 2 SCHC(O)C 6 H 4 -p-NO 2 ( Y 2 ) and (Me) 2 SCHC(O)C 6 H 4 -p-OMe ( Y 3 ) with AgTfO in 2: 1 molar ratio using dichloromethane as a solvent, [Ag(Y n ) 2 ]TfO (n = 1 ( 5 ), n = 2 ( 6 ), n = 3 ( 7 )) complexes were obtained.

Single crystal X-ray diffraction analysis reveals the presence of linear structure for 5 . Characterization of the obtained compounds was also performed by elemental analysis, IR, 1 H- and 13 C- NMR.
