✦ Synopsis
Pair-pair electron repulsion has been suggested to be an important factor . . . . responsible for the abnormally high reactivity of nucleophiles such as ROO-. . . . toward some electrophiles.'
Recently, it has been suggested that widely separated electron pairs may interact strongly. Thus, molecular orbital calculations' and photoelectron spectroscopy3"' indicate that the unshared electron pairs of the diazines pyridazine (I),pyrimidine (II) and pyrazine (III) interact strongly.
Interactions are transmitted both through space and through bonds.
