NCI-Co catalyzed olefin oxygenation reactions were investigated. Among the metals examined, including noble metals, the reaction proceeded specifically on Co catalysts, and nitrogen dopant was crucial for the catalytic activity. The presence of NaBH4 as a hydride source, the corresponding alcohols were obtained in high yields. The substrates bearing a reductant-sensitive functional group were made tolerant by changing the reductant and using an additive, and furthermore, the corresponding ketones were accessed by changing reaction conditions. A preliminary examination of other SOMOphiles suggested that the heterogeneous catalyst systems have the potential to be applied to more general hydrofunctionalization of olefins to form various kinds of bonds. Several mechanistic studies suggested that the reaction proceeded in a heterogeneous manner and formed a radical intermediate on cobalt nanoparticle species.
The Conversion of Phenols to Primary and Secondary Aromatic Amines via a Smiles Rearrangement

The conversion of phenols to 2-aryloxy-2-methylpropanamides (1) and the Smiles rearrangement of these to N-aryl-2-hydroxy-2-methyl propanamides are described; hydrolysis of the latter compounds yields anilines.The scope and limitations of reaction are discussed.Routes, some involving α-lactams, from phenols to N-substituted derivatives of (1) have been developed.Under the conditions of the Smiles rearrangement these secondary 2-methylpropanamides can form directly anilides, N-alkylanilines, or benzoxazinones.
