Oxidation of Transition Metal Complexes with 3,7-Diazabicyclo[3.3.1]nonane-Derived Ligands
A series of new 3,7-diazabicyclo[3.3.1]nonane (bispidone)-derived ligands with phenolic side chains were synthesized. The double Mannich condensation reaction to create the bicyclic bispidone was carried out successfully, though the isolation of the bispidones was not always straightforward. The …

Cytochrome P450 whole cell biohydroxylation of alkanes
… activity with: n-octane > n-decane > n-nonane, caused by a combination of alkane solubility and transmembrane transport. Although n-decane is less soluble in water than n-nonane, the ‘odd-even’ effect of alkanes resulted in high in vivo activity on n-decane. UNIF-LL predictions …
