Opening of the epoxide ring of several arylglycidyl ethers with thiocyanato anion followed by acetylation yielded racemic mixtures of 1-aryloxy-3- thiocyanato-propan-2-yl acetates. A lipase-catalyzed hydrolysis of the acetates resulted in the separation of the enantiomers. The unstable, optically active (S)-1-aryloxy-3-thiocyanatopropan-2-ols, were converted into the corresponding 2-aryloxymethyl thiiranes, which instantly polymerized to yield the optically active oligomers.

The rate of the doping addition in the reactions of 2,4-dinitrophenylsulfenyl chloride with cyclohexene an methylenecyclobutane and of dithiocyanogen with cyclohexene and substituted styrenes in the presence of lithium perchlorate is described by the normal salt effect equation.On the other hand, the rate of formation of the doping products may exceed or lag behind the increase in the total reaction rate.These results were interpreted in the framework of an ion-pair mechanism.
