Using tin(II) chloride to reduce carbonyl to alkene.

Darryl Siemer  Follow
SnCl2/HCl is used to reduce aromatic nitro compounds to amines, I don't believe it'll reduce a carbonyl to an alkene - that's kind of a weird reduction, and doesn't happen in what you described. Your product anthrone isn't an alkene. You reduced a C=O to an sp3 carbon.More

That’s how the scheme is written out, and it’s a question that’s been asked in past exams. We later use activated zinc dust to reduce the anthrone to anthracene, which I believe would have allowed us to fully reduce the anthraquinone to anthracene. Another interesting oddity is that I don’t believe anyone in our lab group was successfully able to reduce the carbonyl using tin chloride as our products did not have the appropriate melting point.More

The mechanism seems a bit obscure, though.More
