REVIEW

 Mild, selective oxidant for alcohols to aldehydes or ketones: Tetrahedron Lett., 2647 (1975); review: Synthesis, 245 (1982). Superior results have been reported with a catalytic amount of acetic acid: Tetrahedron, 46, 4417 (1990). Adsorption of the reagent onto alumina simplifies work-up and enhances reactivity in hydrocarbon solvents: Synthesis, 223 (1980). Improved results have also been obtained in the presence of silica gel, where reaction times are shortened by sonication: J. Org. Chem., 54, 5387 (1989). Oxidation of methylarenes to benzaldehydes has been reported. Selective mono-oxidation of xylenes to tolualdehydes can be achieved: Synlett, 2769 (2005).

[2] Trialkyl boranes are also oxidized to carbonyl compounds, non-terminal boranes giving ketones: J. Organomet. Chem., 162, C9 (1978) and terminal boranes giving aldehydes: J. Organomet. Chem., 172, C20 (1979). Similarly, aldehydes can be prepared from terminal alkenes by oxidation of their adducts with thexylborane: Synthesis, 151 (1980).
