Title: Benzaldehyde -> p2p
Post by: benzoateFan on July 08, 2004, 06:19:00 AM

Guys dont tell me to UTFSE cause i have.... repeat I HAVE.

i wanna know how to get to p2p from benzaldyde which has Been PROVEN not just theory on paper if thats ok..thanks

Look for posts from the username two dogs its caslled"new method for P2P", and its not theory.

Post by: Rhodium on July 08, 2004, 07:00:00 AM

The easy way:

Phenyl-2-Nitropropene (P2NP) from Benzaldehyde (https://www.thevespiary.org/rhodium/Rhodium/chemistry/phenyl-2-nitropropene.html)

(https://www.thevespiary.org/rhodium/Rhodium/chemistry/phenyl-2-nitropropene.html)

Phenyl-2-Propanone (P2P) from Phenyl-2-Nitropropene (P2NP) (https://www.thevespiary.org/rhodium/Rhodium/chemistry/phenylacetone.html#p2np)

(https://www.thevespiary.org/rhodium/Rhodium/chemistry/phenylacetone.html#p2np)

The high-tech way:

Phenyl-2-Propanone (P2P) from Benzaldehyde and a Phosphonium Ylide (Wittig reaction) (https://www.thevespiary.org/rhodium/Rhodium/chemistry/phenylacetone.html#ylide)

(https://www.thevespiary.org/rhodium/Rhodium/chemistry/phenylacetone.html#ylide)

Then benzylic -OH reduction to P2P.
