Fermenting baker s yeast transformed 2-butanone oxime containing 44% excess of the ( )-isomer into optically active (R)-2-aminobutane in 58% enantiomeric excess. The chiral amine was also obtained in 24% e.e. from the oxime acetate but the oxime methyl ether gave a racemic product (equation 2)16.

Dining preparation of tris(ketoximino)silanes, two violent explosions attributed to acid-catalysed exothermic rearrangement/decomposition reactions occurred. Although these silane derivatives can be distilled under reduced pressure, the presence of acidic impurities (e.g. 2-butanone oxime hydrochloride, produced during silane preparation) drastically reduces thermal stability. Iron(III) chloride at 500 ppm caused degradation to occur at 150°, and at 2% concentration violent decomposition set in at 50°C.

The 2-butanone oxime could be readily separated from the oximes arising by interaction of the nitric oxide with the initially formed radicals from the decomposition of the substrate. By this mixed-inhibitor technique, low concentrations of NO could be used, and the NO(4II)-photosensitization of the alkane could therefore be obviated.
