How to convert ethanol to 1,1-dichloroethane? How to convert ethanol to 1,1-dichloroethane?

My approach: Convert ethanol to ethene followed by $\ce{HCl}$ addition. But that's no use. Well if it is possible to create gem-diol from here, then maybe it can be done. But not getting a suitable reaction. Can't seem to figure out anything. Please help!

A standard route for producing gem-dichloro compounds involves treatment of a ketone or aldehyde with $\ce{PCl5}$ (see the second to last paragraph in the "Chlorination of organic compounds" section here and page 18 here).

Therefore, you could carefully oxidize your ethanol to acetaldehyde and treat it with $\ce{PCl5}$.
