Bis-silylenephosphorane (silylene = silanediyl)versus bis-methylenephosphorane: a theoretical study
Abstract
On the basis of ab initio calculations bis-silylenephosphorane as compared with bis-methylenephosphorane suffers from Jahn–Teller distortion as a consequence of the stability of (nonbonding) Ione pairs at the terminal SiH2 units, causing a strengthening of the phosphorus–silicon bond.
