Title: mdp-2-nitropropene -> mdp-2-propanone
Post by: phenethyl_man on June 14, 2004, 08:46:00 AM

hi,
.. trying to reduce mdp2np to the ketone a la shulgin and/or as stated in this document:

https://www.thevespiary.org/rhodium/Rhodium/chemistry/mdp2p.piperonal.html (https://www.thevespiary.org/rhodium/Rhodium/chemistry/mdp2p.piperonal.html)

said document states a 20% drop in yield if reduced powder is not used, however, i can't obtained it reduced, except by freight, since apparently it is quite combustible.

are there any other options here?  can regular iron powder be reduced w/o special equipment?

any input appreciated.

Hi! Perhaps you should try to reduce your MDP2NP with SnCl₂ in acetone/ethylacetate to the oxime and hydrolyze to the ketone in same flask, followed by a simple steam distillation of the MDP2P. It is VERY easy and gives good yields and a very pure product if done carefully. There are many threads about it...

(just a suggestion)
