Hi Everyone,

 

I'm trying to confirm a synthesis of an amide. I ran an IR and I have a peak at 1641 and 1562 cm-1, so I'm assuming it's a secondary amine.

 

I wanted to know if there were any chemical tests I could run to confirm the presence of an amide? I only remember amine tests from organic (Hinsberg, Acetyl Chloride, etc)...

 

I have very limited amounts of solution (15 mL), so I can't afford to run experiments that give false positives or false negatives.

 

Can anyone suggest any tests?

do you have access to an nmr machine? that'd be pretty conclusive...

 

otherwise you could try this

Do any of the starting materials absorb at 1641 and 1562?

If you started from an acid halide does the corresponding acid absorb there?

If not then the evidence is pretty good that you have an amide.
