| Abstract: | Four neutral rhenium compounds were examined by electrospray ionization mass spectrometry. Acetonitrile solutions of (Ind)Re(CO)3 (Ind = indenyl) and (Cp)Re(CO)3 (Cp = cyclopentadienyl) gave rise to Re(CO)3(CH3CN)3]+ ions. This is indicative of a reaction with the solvent, although these compounds do not react with acetonitrile under regular laboratory conditions. In contrast, (Ind)Re(CO)2(butyne) and (Cp)Re(CO)2(butyne) did not lose their aromatic hydrocarbon ligand upon ionization; the predominant product ions generated upon electrospray ionization were (Ind)Re(CO)(CH3CN)(butyne)]+ and (Cp)Re(CO)(CH3CN)(butyne)]+, respectively. |
