# Reaction of phenol and zinc dust

There is a reduction reaction of phenol with zinc dust which is found in many books.

$\ce{Ph-OH + Zn -> Benzene + ZnO}$

However, a simple google search fails to explain anything about the reaction. So, I put forth my questions:

1) What is the name of the reaction and who invented it?

I have already done a google search, but it yields no results. My textbook also mentions nothing about the inventor of the reaction, or any name of the reaction. I understand that every reaction might not have a name, but at least it must have an inventor. You can't say that the reduction of phenol by distilling it with zinc dust is known from time immemorial. Can you?

2)What is the reaction mechanism of the reaction?

This and this page writes about a mechanism of the reaction. If drawn, I suppose it would look like this: It would certainly explain the formation of biphenyl and hydrogen ( if they are indeed formed). But the problem is that no reference is given in the answers. There is at least one book or paper which wrote about the mechanism.
