As a result of interactionof1-xlor-3-noniltio-2-propanol with o-bromfenol was sintesized 1-(o-bromfenoksi)-3-mo-niltio-2-propanol. From the condensation of the last with aromatic izosionats and izotiosionats corresponding carbomates and tiocarbomats were sintesized. Their physical and chemical peculiarities have been investigated and their antimicrobic peculiarities were studied.
