### Theory¶

I’ve finally sucked it up and started researching/drawing up some mechanisms, and I’m relatively confident with this amination2 ([fig:amination]). Other mechanisms are proving more difficult to pin down though. while I can find a mechanism for the oxidation1 (1$$\ce{->}$$2) it’s specific to hexenes. I can find evidence that the process works for aromatic compounds3, but can’t find a mechanism to prove it.

The reduction (2$$\ce{->}$$3) is also proving difficult, and in trying to figure out the mechanism by hand, I keep getting stumped by the lack of water or acid, that would otherwise contribute protons to the solution.

### THF distillation¶

After the weekend, the THF that was distilled off was combined with fresh benzophenone, fresh sodium and put back on the still to be refluxed.

### Synthesis of 1 (AS03) (attempt 3)¶

coming back after the weekend, nothing had crystallised out of the flask and so more toluene was added and the mixture was dried with the rotary evaporator. The crude leftover solution was recombined with minimal DCM and left to slowly crystallise overnight.
