Title: Conversion of Nitrostyrene
Post by: roger2003 on December 17, 2003, 12:47:00 PM
It is possible to convert Nitrostyrene to

Cinnamic acid
and
Phenylacetic acid
????

The Nitro Group in Organic Syntheses p. 163
(Conversion of Nitro Compunds into Cabocyclic Acids)

…a very efficient related reaction using a mixture of sodium nitrite and acetic acid in DMSO (at 30° C ; 6 h) has been reported. Because carbon-carbon double bonds and triple bonds and other various functional groups are compatible with this reaction conditions……

JOC 62, 234 (1997)

Will this yield cinnamic acid ?
