The reaction of electrophilic terminal phosphinidene complexes with enolizable ketones: C–H vs O–H vs C–C insertion of phosphorus

Abstract

Transient [PhP → W(CO)₅], as generated from the appropriate 7-phosphanorbornadiene precursor, reacts at 120 °C with various enolizable ketones or β–diketones to give the products resulting from the insertion of phosphorus into either the α-CH, the enol OH, or the acyl-CH₂ bonds.
