CHAPTER 4 Secondary (Agostic Si-H/Electrostatic C-F) interactions in alkaline earth-based catalysts
Abstract
The design and implementation of a selection of homogeneous alkaline earth (Ae) catalysts and precatalysts for hydroamination and hydrophosphination of olefins and for ring-opening polymerization of cyclic esters are surveyed. Emphasis is placed on the three large elements calcium, strontium and barium. The role of Ae⋯H–Si and Ae⋯F–C noncovalent interactions in the stabilization of (pre)catalysts is highlighted.
