Transformation of neutral rhenium compounds during electrospray ionization mass spectrometry [PDF]
, 1997 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.
