Secondary phosphine oxides O=PHR2 (SPOs) were identified as multitalented preligands for the chemoselective Pd-catalyzed oxidation of alcohols by a hydrogen-abstracting methodology. SPOs were found to promote the hydrogen-abstraction step as well as hydrogen transfer to a Michael acceptor by generating a putative active H?Pd species. The catalytic system operates under neutral conditions and was proven to be compatible with various electrophilic and nucleophilic functionalities within the substrates as well as water- and air-sensitive functional groups.
Iron(III) mediated transformations of cyclopropyltrimethylsilyl ethers. Part 1. Free radical tandem ring expansion-cyclisation reactions for the rapid construction of bicyclic ring systems

Treatment of a number of cyclopropyl trimethylsilyl ethers with anhydrous ferric chloride in dry dimethylformamide leads to diastereoisomerically pure bicyclic chloro ketones by a novel tandem ring expansion-cyclisation sequence.The reaction is thought to proceed by a mechanism involving the intermediacy of a cyclopropyl alkoxy radical.
