Interesting method to Phenylnitroethanes
« on: September 23, 2004, 08:06:00 PM »



..as read in "the Nitro Group in Organic Synthesis" page 127 the book is found here...

Note: edited by java and corrected by rhodium, should read phenylnitroethanes

Phenylnitropropenes? I can only see a synthesis of Phenylnitroethanes... How is Sulfonylnitromethane best prepared?

In my wishful thinking I made an error , sorry about that, as for the arylsulfonylnitromethane synthesis , alI can gather it's a type of Merrifield resin bound nitroacetate and I wasn't able to locate a reference that may have something to do with their preparation.....java

Nitroethane from arylsulfonylnitromethane......

Thank you SpicyBrown for the study , hence the synthesis of the arylsulfonylnitromethane is  found and also it seems that nitroethane  as well as  phenylnitroethane is made and the sulfonyl group is removed as per the original posting ..........java

I feel the need to connect this thread with the analogous one:

The allkylation mechanism is the same, but removing the –COOMe group is way easier than –SO2Ph. Not to mention that alkyl nitroacetates are way more accessible (even by simply nitrating ethylacetoacetate!).
An interesting method otherwise and potentialy useful for those that have access to such reagents.
