I am doing a green chemistry project as an undergraduate and need the balanced equation to complete the calculations. I cannot find the right information online so any help would be greatly appreciated.

  • $\begingroup$ Please could you tell the products produced after the reaction other than the target molecule. What does the borane complex become after the reduction? Something like HOBH2/THF or OBH/THF? $\endgroup$ – mmmmm Feb 14 '19 at 12:39

The reduction of secondary amides with BH3 requires 3 equivalents, mechanism shown below image sourced from here. The borane becomes HB=O which may transform further depending on work up.
