Herein we shed light on the mechanism of the reaction of epoxides with ammonium thiocyanate to give the corresponding thiiranes in water, and we present a computational mechanistic model for this highly useful reaction.

ABSTRACT Mo(CO)6 converts a broad range of thiiranes to the corresponding alkenes in high yields under neutral conditions. It has been found that this protocol is chemoselective and tolerates a variety of functional groups such as chloro, bromo, fluoro, ester, methoxy, ether and keto. GRAPHICAL ABSTRACT

A biocatalytic thionation method is presented for the enantioselective synthesis of thiiranes from epoxides by a halohydrin dehalogenase catalyzed kinetic resolution approach using thiocyanate as a sulfur donor. Various chiral thiiranes bearing aryl and alkyl substituents were synthesized in good yields and enantioselectivities by using recombinant Escherichia coli cells expressing the engineered halohydrin
