Synthesis and study of the lubricating properties of some thiiranes

A series of novel thiiranes were synthesized, and their lubricating properties were studied. It has been found that they improve the antiscuff and antiwear properties of gear oils and therefore can be used as additives. The relation between the structure of the synthesized thiiranes and their lubricating activity was revealed.

Symmetric bisthiiranes

Symmetric bisthiiranes were synthesized by reactions of the corresponding bisoxiranes with thiourea in the presence of methyl alcohol. The initial bisoxiranes were obtained by cyclization of bis(chlorohydrins) which were prepared by reaction of p-phenylen
