Abstract

A general method for location of double bonds in isomeric alkenes, alkynes, alkadienes, fatty acids (esters) and alkenyl acetates (often found as pheromones) has been developed. Reaction of olefins with Fe(CO)** plus , generated by electron impact on Fe(CO)//5, in a CI source yields iron-olefin complexes that rearrange by an allylic insertion mechanism. Upon collisional activation, the resulting bis-olefin complex preferentially loses the smaller olefin. Additional information may be derived by examination of the product ion structures. An advantage of this technique is that elemental compositions can be determined by using high resolution mass spectrometry.
