    organic chemistry-reaction mechanisms

    1. The problem statement, all variables and given/known data In pyrrole the electron density is maximum on which carbon atom? [​IMG]so if the numbering starts from nitrogen, the carbon on the right side of nitrogen let it be numbered as 2 and the next one as 3 and so on... which of the following...

    Really Need Help With Two Organic Mechanisms...

    I am trying to draw out a complete mechanism for a 7-step synthesis and there is one reaction I can't quite figure out. I have to go from 2-iodophenol to O-(2-iodophenyl)-N,N-diethylcarbamate using the reagents and conditions: K2CO3, N-N-diethylchloroformamide, CH3CN, reflux, 2h. Any help...
