  11. I think I saw somewhere an organometallic reagent that will methylenate the
  12. carbonyl of an ester but I don't remember what it is.  Does Tebbe's reagent
  13. do this or is it limited to aldehydes and ketones?  What reagent does?

  19. Does it work for amide carbonyls as well?

  21. Thanks for your help!
