✦ Synopsis

The reactions of o-, m-and p-benzyne anions and the phenide ion with a series of neutral reagents are described. The m-and p-benzyne anions display similar behavior towards acids, NO and

, analogous to that of phenide ion but clearly di †erent from that of o-benzyne anion. The strongly basic and nucleophilic character of m-and p-benzyne anions dominates their reactivity, and radical-type reactions are generally not observed. Novel bifunctional reactions between m-and p-benzyne anions and both and NO are observed in CS 2 which two sequential S-atom abstractions and two NO additions, respectively, take place.

This paper reports a gas-phase study of ligand effects on the reactivity of the organometallic distonic ion Fe(p-benzyne) Á . New organometallic distonic ions are generated by introducing a benzene ligand onto the metal center of Fe(p-benzyne) Á . We were interested in whether the reactivity of the
