Dissociative Interchange Pathway
Interchange pathways apply to substitution reactions where intermediates are not observed, which is more common than pure dissociative pathways. If the reaction rate is insensitive to the nature of the attacking nucleophile, the process is called dissociative interchange, abbreviated Id. An illustrative process comes from the "anation" (reaction with an anion) of cobalt(III) complexes:
-
- 3+ + SCN- {, NCS}2+
- {, NCS}2+ 2+ + H2O

Famous quotes containing the words interchange and/or pathway:
“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot function without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”
—Howard Brenton (b. 1942)
“Socrates drinking the hemlock,
And Jesus on the rood;
And millions who, humble and nameless,
The straight, hard pathway plod—
Some call it Consecration,
And others call it God.”
—William Herbet Carruth (1859–1929)
