Mechanism of Formation of Ni-(S)-Gly-BPB Complex/Nickel coordination
« on: January 05, 2011, 10:57:01 AM »
Hello everyone..

I have to figure out the mechanism for the formation of Ni-(S)-BPB-Gly ( the complex is shown here: http://discoverylab.eu/DL0013.html) for a lab report...

Despite searching numerous journals I am still struggling to devise the mechanism of this formation  ???

I can see that there is a new peptide bond formed between the glycine and the carbonyl group on the BPB compound.. but I don't see how I can explain mechanistically how the nickel gets involved.

If anyone can shed any light on this or has any ideas I can explore.. I would be really grateful.

Thanks!

What Ni species do you start with?

Ni(NO3)2.6H2O
which is stirred under nitrogen with BPB, glycine and MeOH
