The sulfur can restore peroxide to the corresponding binary. For example, in the reaction below, the cycloidne is first added to a single line -line oxygen ring to become an unstable ring oxide intermediate, and then restored with sulfur to get the corresponding diol.

Therefore, sulfur sulfur is also used in olefin ozone, that is, restore the middle body ozone is the corresponding cymbal compound. Metolo ether can also perform similar reactions, but due to its volatile and unpleasant smell, its application is limited. The sulfur is difficult to volatilize and there is no smell, so there are more applications

The sulfur can also be used in the construction of pyrimidine. The specific process is: the amino group in the sulfur and the alcohol contraction in the amino group in the sulfur and the β-diabolic compound, and then desulfurize.
