Really quickly, i'm going to assign the r group that's given, so i don't have to keep drawing it.
00:10
So we know that our molecule starts off looking like this with a funnel ring.
00:16
And we're just going to say that this section of the molecule is just the r group.
00:24
And so we can redraw it smaller like this.
00:28
Okay.
00:29
And so in the first part of the mechanism, the oh loan pair, it's going to push down and the carbonyl oxygen is actually going to attack the thionyl chloride.
00:50
This is going to result in the following intermediate, like so.
01:03
Next, chlorine is lost from the thionyl chloride, reforming or partially reforming the thionyl chloride molecule.
01:31
This chlorine can then pick up the proton on top of the oxokreferral.
01:38
Carbonium ion, just kind of a proton transfer step like so.
01:59
Right, so this kicked this lost hcl here.
02:08
From here, the chloride ion can then attack at this position...
