The use of ionized vinylamine [CH 2 = CHNH 2 ] + . in locating double bonds in olefinic compounds is illustrated on a series of octene molecules. It is demonstrated that a cyclobutanation process leads to intense diagnostic ions which unambiguously allow the position of the C = C bond on the aliphatic chain to be determined. The described experiments were carried out in a Fourier transform ion cyclotron resonance mass spectrometer. Under these conditions high reaction efficiencies and pronounced regioselectivity are observed. © 1997 John Wiley & Sons, Ltd.
