Hello everybody! I'm starting my chemistry degree's final project and I'm working on some organic synthesis, got the compound I wanted when triflic acid was as a catalyst on a Friedel Craft (acylation) reaction. For the same reaction I've tried using some lewis acids that were reported for similar reactions such as ZnCl2 and Sc(OTf)3 but, surprise, those didn't work as expected (way lower yield if any). This week I also tried methanesulfonic acid as well and just got a messy and dirty reaction that didn't show any product after trying doing workup with sodium bicarbonate in order to neutralize the acid so I can run a decent TLC.
So, I only got the reaction to work using triflic acid. I'd like to find a cheaper reagent that can do the same work, do you know anyone? Also I'm opened to suggestions of any type. Please have in mind that I'm just a student so I may be ignoring some stuff 😅.
Thank you! 🇦🇷
I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
Do your worst!
I'm surprised it hasn't decade.
For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
I said "hey look, an escaPEA"
No one near me but it didn't half make me laugh for a good hour or so!
Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂
It really does, I swear!
Because she wanted to see the task manager.
They’re on standbi
Heard they've been doing some shady business.
Pilot on me!!
Nothing, he was gladiator.
Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.
This sub is mostly just NSFW puns now.
If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.
Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.
What did 0 say to 8 ?

This morning, my 4 year old daughter.
Daughter: I'm hungry
Me: nerves building, smile widening
Me: Hi hungry, I'm dad.
She had no idea what was going on but I finally did it.
Thank you all for listening.
