When optically pure 2 3 dimethyl 2 pentanol was subjected to dehydration a mixture of two alkenes was obtained Hydrogenation of this alkene mixture gave 2 3 dimethylpentane which was 50% optically pure What were the two alkenes formed in the elimination reaction and what were the relative amounts of each" ... 

Different regio-selectivities are found in the sMMO-catalyzed hydroxylation of branched alkane. Sterically hindered tertiary carbon is not reactive. In the oxygenation of 2,3-dimethylpentane catalyzed by sMMO from M. capsulatus (Bath), 3,4-dimethyl-2-pentanol is the sole product as shown in eq. (6) The sMMO-catalyzed hydroxylation of isopentane occurs mainly at the primary carbons of the alkane (see Table 3). These different selectivities may depend on shape and size of the substrate binding site of sMMO. These reactivities are similar to the (o-hydroxylation of -alkane catalyzed by cytochrome P-450 [74].
