“…16,17 The alkylation of 1 provides a facile route for the generation of functionalized thiolate ligands . 21 An electrospray ionization mass spectrometry (ESI-MS) based screening of the reactions of 1 with a variety of alkylating agents indicates the possibility of generating dinuclear platinum complexes containing a range of thiolate ligands. 16 This methodology has been used to generate coordinated functionalized thiolate ligands (-SR) on 1.…”

The reactivity of the metalloligand Pt2(μ-S)2(PPh3)4 with the boron-functionalized alkylating agents BrCH2(C6H4)B(OR)2 (R = H or CMe2) was investigated by electrospray ionization mass spectrometry (ESI-MS) in real time using the pressurized sample infusion (PSI). The macroscopic reaction of Pt2(μ-S)2(PPh3)4 with one mole equivalent of alkylating agents BrCH2(C6H4)B{OC(CH3)2}2 and BrCH2(C6H4)B(OH)2 gave the dinuclear monocationic µ-sulfide thiolate complexes [Pt2(µ-S){µ-SCH2(C6H4)B{OC(CH3)2}2} (PPh3)
