How does diazomethane react with a diketone?

  1. Jan 3, 2014 #1
    1. The problem statement, all variables and given/known data
    What are the products when 1-phenylbuta-1,3-dione reacts with diazomethane in
    presence of ether?

    2. Relevant equations

    3. The attempt at a solution
    I tried to do it this way:
    Since carbonyl carbons of 1-phenylbuta-1,3-dione , one of them might get attacked by the positively charged nitrogen of diazomethane ;and the oxygen ,will therefore (maybe?), bond with the other nitrogen . And then I think the ether will do something but the problem is I can't reason out what happens next or is this approach even correct or not.:confused::cry:
    Is this some named reaction ? I tried to google it and stumbled upon the Nierenstein reaction but that is not exactly this reaction , right?:confused:
    Any hint or help will be REALLY appreciated.
    Thanks in advance.:biggrin:
