Thanks, that's very interesting and useful.
I'm a bit confused tho.
On
https://www.thevespiary.org/rhodium/Rhodium/chemistry/tcboe/chapter7.html
it shows piperonal, or 3,4 methylenedioxybenzaldehyde, being condensed with nitro
ethane to yield a nitrostyrene- a three-carbon-long substituent.
In US Pat. 2,597,445 it uses a benzaldehyde with an alkali metal salt of 2-nitro
propane, yet still produces a 3-carbons-long ring substituent.
can you explain how this works?
One, having lent one's textbook to a friend, may probabaly be asking questions one normally wouldn't... one is endeavouring to reclaim it
What is meant by "an alkali metal salt of 2-nitropropane", in the patent? I know what an alkoxide is, but what's that?
