Notes. The acid strength of iodine cyanide
Abstract
Measurements of the enthalpy of complex formation of diethylacetamide, diethyl sulphide, and pyridine with iodine cyanide have enabled us to calculate the EA and CA parameters of ICN and draw an acceptor-order plot explaining the sequences: IC1 > I2 > ICN towards soft bases and IC1 > ICN > I2 towards hard bases.
