Can you help me identify reagent (i), Compound 8 and
Compound 12 in the reaction scheme?
You have laboratory data on all the compounds in the
synthesis, however the amount of data available to you varies. Some
have the entirety of the spectral data, others have as little as
the elemental analysis. Use the laboratory data to help you
discover which reaction has been performed.
The lab data for Compound 8 and 12 is as
follows:
You can use any...
