is reduction of nitro compounds by Sn,hcl regioselective ie even if a double bond is present it will reduce no2 to nh2

waterdemon

Yes,
The Reduciton of Nitro Compounds by Sn/HCl is regioselective
That means irrespective of where is te double bond in pos.
with Double Bond it is going to reduce -NO₂ Group to -NH₂
Group.

One such Example is:

When NitroBenzene Compound Reacts with Sn/HCl we will
get the end compound as Aniline.

Means Benzene has a NO₂ group at main position and when
reacted with Sn/HCl it gets -NH₂ at the same position.

Hope it helps.

thanks,

but can i take it for granted that the same should happen with an aliphatic nitro compound with a double bond.coz benzene is a stable compound and doesnt undergo reduction that easily,so maybe it is easier to reduce no2 rather than benzene- double bond.but thats not the case when it is an aliphatic compound is it
????

shevchenko

pls answer,anyone

waterdemon

Yes even in the case of Aliphatic Nitro Compound with a (=)
double bond ,when reacted with Sn/HCl We will get:
NO₂ Group Replaced by -NH₂ Group.

But an Exception is there:
In
para-dinitrobenzene when reacted with Sn/HCl it does not react but to replace NO₂ with -NH₂ group it is reacted
with (NH₄)₂S.

Hope you find it useful.
plZ rate if useful.
