An efficient dynamickineticresolution protocol using a single enzyme is described. Both the kineticresolution and substrate racemization are catalyzed by halohydrin dehalogenase from Agrobacterium radiobacter AD1 (HheC). The HheC‐catalyzed reaction of epibromohydrin and 2‐bromomethyl‐2‐methyloxirane with sodium cyanate afforded 5‐substituted 2‐oxazolidinones in high yields (97% and 87%) and high

In attempt to synthesize suitable [FeFe] hydrogenase model complexes, 2-methoxypropane-1,3-dithiole and 4-methyl-4-hydroxy-1,2-dithiolane were reacted with Fe-3(CO)(12) to give the respective complexes [Fe-2(CO)(6)(H3COCH(CH2S)(2))] and [Fe-2(CO)(6)(HOC(CH3)(CH2S)(2))]. The compounds were characterized by H-1 and C-13 NMR spectroscopy, mass spectrometry and elemental analysis. In addition, their electrochemical properties were investigated by cyclic voltammetry and compared with that of [Fe-2(CO)(6)(HOC(CH2S)(2))] known from literature. (C) 2010 Elsevier B.V.
