Silanes in organic synthesis. 9. Enesilylation as a method for 1,2-carbonyl migration within ketones and for conversion to 1,2-transposed allylic alcohols
Structurally diverse arylchlorides were silylated with sodium silylsilanolate reagents in the presence of a Ni(cod)2 catalyst complexed with a phosphine ligand; PMe2Ph for electron-rich substrates, and PCy2Ph for electron-deficient ones. The mild reaction conditions allowed the silylation of various arylchlorides including functionalised drug molecules.

A trimethylsilyl substituent is used to control regiochemistry in the metal-ammonia reduction of several naphthalenes, and is subsequently removed resulting in a “Misoriented Birch Reduction.”
