High basicity of phosphorus–proton affinity of tris-(tetramethylguanidinyl)phosphine and tris-(hexamethyltriaminophosphazenyl)phosphine by DFT calculations
Abstract
It is shown by approximate but reliable DFT calculations that the title compounds represent very strong superbases in gas phase and MeCN. In particular, tris-(hexamethyltriaminophosphazenyl)phosphine has a
