The construction of a two-stage ion beam mass spectrometer is described. Ions formed by electron impact are focused into a beam which enters a reaction vessel containing neutral molecules at a relatively high pressure. Secondary ions formed by reaction between the primary ion beam and neutral molecules are repelled out at right angles to the primary beam into a conventional magnetic analyser. The instrument was calibrated using the known Ar + + Ar → Ar + Ar + electron transfer reaction. It was then used to study the reaction of acetylium (CH 3 CO + ) and nitronium (NO + 2 ) ions with aromatic compounds. The principal secondary ions were those involving electron transfer from the aromatic nucleus, but in addition ions of the type C 6 H 6 NO + 2 formed by addition of the primary ion to the aromatic compound were detected. However, the relative ‘yield’ of adduct ion from different aromatic compounds showed little correlation with the reactivity of these compounds towards acylation or nitration in solution.

AbstractWe describe in this paper an experiment involving an electronically conductive polymer (ECP) which, to our knowledge, has not been described previously. A free-standing ECP (polypyrrole)-based membrane separates a solution of an electron donor from a solution of an electron acceptor. Because the ECP is both electronically and anionically conductive, the membrane can transport electrons from the donor solution to the acceptor solution, and anions in the opposite direction, such that a sustainable electron-transfer reaction is driven across the ECP membrane. We demonstrate such transmembrane electron/ion-transfer processes using both an inorganic and a biochemical electron donor/acceptor system. The biochemical case is of particular interest because we show that the reduced form of the enzyme glucose oxidase can give its electrons directly to the synthetic metal. Direct electron transfer is usually not possible at inorganic metals.
