Clipping is a handy way to collect and organize the most important slides from a presentation. So at some point during Org 2, you will probably be expected to learn a whole slew  of mechanisms. What if you could cut down the amount of time you spent doing these mechanisms by a factor of six?
Whereby the nucleophile adds to the carbonyl carbon, forming a new bond and breaking the [PI] bond beween the carbon and oxygen.
Although the material is spread out over several chapters, the hidden pattern in their mechanism should come in handy when it comes to exam time. I’ve been trying to come up with a good mnemonic for this.¬† Piranhas Attack People Every Day? I always assumed that the making of anhydrides was a little more trickier than what has been presented here. It’s not a very broadly useful method since it can only make symmetrical anhydrides, but this almost certainly how commercial acetic anhydride is made.
Well, water and toluene (as well as water and benzene) form an azeotrope, and boil off together. Why may step three and four be as shown above rather than your described mechanism with an intramolecular proton transfer? I’d go a bit perverted if it were one of my organic chemisty students, but I like the idea of an acronym.

In the conversion of carboxylic acid to anhydride mechanism, the second structure isn’t right, the proton is on the wrong oxygen.

That means writing out and learning a whole bunch of different steps for each of these reactions.
The six reactions listed might look different, but they actually have EXACTLY THE SAME MECHANISM. This means the oxygen (or nitrogen) has less electron density to share with the carbonyl carbon. Note that the neutral nucleophile is positively charged and the (former) carbonyl oxygen is neutral.
I assumed that for an eg, acetyl Chlorides were required due to the chloride being a better leaving group. The first is the way you mentioned – adding carboxylates to acid halides, and this forms anhydrides.
Use benzene or toluene as co-solvent, the water will be driven off, allowing the reaction to go to completion.
So if i am getting this right, the co – solvent and toluene is somewhat bonding well, thus allowing the water to be separated via a DS trap.

The distillate ends up in the Dean Stark trap, and the water, being more dense than toluene, settles at the bottom and doesn’t come out.
The densities are pretty close, and under reflux concoctions DS would be out, so perhaps just a HCl catalyst, with acetic acid under reflux with a (DRY) CaCl2 drying tube fitted at the end.
What I do not understand, and feel I need to, is how can carboxylates bond well with say methyl benzene. So I’d take it the anhydride would be within the mix of the toluene, carboxylic acid used, and as stated the water is now removed. I understand, I think, that the carbonyl is more basic compared to the OH group on the carboxylic acid, but it seems to me, having both molecules(carbonyl functional groups) protonated, would be a problem. So, for example, instead of PAPED I would use PATED (or RAPED) and make it the Penis (Proton) Added himself, Transferred himself, got shit on (Eliminated), and De-Penified (got cut off). As you go to lower pH, you’ll start to protonate the carbonyl oxygen (through the mechanism mentioned in this post) which results in a faster reaction.
I wish my chem Professors would allow me to explore this, say with butanoic acid – as stinky as it is, but bypasses the issue of anhydrides and their legalities with respect to acetic and propanoic. So Ive tried to figure out how a chemist would optimize only one of the acids being protonated, and can only come up with a speedy addition of the acid catalyst, to an already under mild reflux conditions.
So P for Penis (and Proton), Added, Transferred, got shit on (Eliminated), and cut off (Bobbit style).
The longer the acid catalyst remains with the molecule in question, the longer it has to protonate both of the carbonyls.
