Effect of phosphoryl and thiophosphoryl groups on CH acidities

  • Published:
Theoretical and Experimental Chemistry Aims and scope

Abstract

It is shown that the CH acidities of phosphoryl and thiophosphoryl compounds depend on the substituents attached to both the carbon atom and the phosphorus atom and comply with Hammett dependences; the parameters of the correlation dependences are very close for the two types of compounds, and this makes it possible to propose a general equation for calculating the pKα values of CH acids that contain a phosphoryl or thiophosphoryl group.
