Stability of Charge-Transfer Complexes of CS2 with PH3 and Its Derivatives: Ab initio MRSDCI/CASSCF Study

Article abstract of DOI:10.1002/hlca.19940770712

While trialkylamines and dialkyl(phenyl)amines do not react with CS2 in the sense of an addition reaction, the analogous phosphines react smoothly.Attempts to interpret the reaction course on the basis of semiempirical, HF, MP2, and MP4 calculations of energy changes failed completely.To understand why Me3P or Me2PhP react so vigorously (liquid phase, 300 K) with CS2, CASSCF and MRSDCI calculations must be carried out.
