The present invention provides a method for producing a diol having a specific structure in high yields while keeping high selectivity. Provided is a method for producing a diol having a specific structure by oxidizing an olefin having a specific structure in the presence of a ruthenium compound.

Described herein are polymorphic forms of 1,6-dibromo-1,6-dideoxy-dulcitol (dibromo dulcitol or DBD), which is a known antitumor agent. Also described are methods of making these new crystalline polymorphic forms as well as methods of using these polymorphic forms to treat cancer.

The present disclosure relates to a recycling method for producing dimethyl carbonate and dimethyl carbonate derivatives. The process is unique in that it produces a by-product that can be re-used in the process as a raw material for repeating the process. For example, when the process is directed to synthesizing dimethyl carbonate, glycerol is used as a starting material. Glycerol is also a by-product produced during formation of dimethyl carbonate, and therefore it can be re-used as starting material to generate more dimethyl carbonate.
