Abstract
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)4]+ and Pt2(μ-S){μ-S+CH2(C6H4)B(OH)(O–)}(PPh3)4. The products were isolated as the [PF6]– salts and zwitterion respectively, and fully characterized by ESI-MS, IR, 1H and 31P NMR spectroscopy and single crystal X-ray structure determinations.
