I know DIBAL-H reduces carboxylic acids and some derivatives, but couldn’t find out about its reaction with acid anhydrides. Do these react? And what are the by-products (if any)?

  • $\begingroup$ I haven't been able to find any references for this but my instinct is that Dibal-H will react with anhydrides, probably to give aldehydes $\endgroup$ – Waylander Sep 2 '18 at 15:38
  • $\begingroup$ @Waylander ... yes, that’s what I thought, too, but I couldn’t find a reliable source to verify $\endgroup$ – aeishna Sep 4 '18 at 5:43
