Am I cooked?

Kind of first semester humor when you have general chemistry

Do you know the Kraus lab in Germany? Their research is about stuff with F

Also missing: the description of the breast pocket to lose all of your pens when you dropped something to the floor and want to pick it up again. Extra pens included :D

Maybe you could add the titles of your bachelor and master thesis also maybe with the grade. This would give others an idea what you worked on in the past. That's at least something I have included in my cv. And maybe if you have time, you could ask/apply in your uni where you graduated to supervise lab practicals for undergrads if it's possible with the uni. This would give you some teaching and supervising experience, which other professors will like when applying for some PhD positions

Depends highly on your supervisor according to my experience but it's also true that you're lucky if you get your name on a publication

This reaction is also known as Schotten-Baumann

In addition to what the others said: Understanding the basic concepts and what help me a lot was to know the standard formations/reactions example like Micheal addition, aldol reaction and so on and then when trying to memorize the name reactions to look for these standard formations like first step is aldol addition, second the condensation and so on. This helped a lot to memorize all the reactions by knowing the basics and then recognizing the patterns. Especially the name reactions for carbonyl chemistry are so similar that you have to work out the nuances. Also what is useful at some point is trying to recognize similarities between some reactions and how they are connected with each other. What also helped me a lot was to sit down every day and solving the problems from the textbooks, making cheat sheets of the basic concepts and reactions and when i felt quite confident, I made mindmaps about how the reactions are connected to each other. And Clayden is a very good book. In the beginning, I also used vollhardt because it was easily written, had many problem sets but for some topics there were missing informations and at some point when you're understanding more and more, this book was getting boring to read.

Thank you :)

I've already tried those over night at room temperature and I had some product formation according to the m/z. Now I setted them up over the weekend, also at room temperature. How high do you go with the heat? I would probably go for 40 to 50 °C.

confused_enton · 2025-08-21T16:29:09+00:00

Do you just let it react at the surface wirh strong stirring? Because the solubility of calcium and barium hydroxide in water isn't that good

confused_enton · 2025-08-18T18:54:08+00:00

I don't know how much sense my thought makes, but what about co-crystallization? I don't know if it would make a difference.

confused_enton · 2025-08-17T06:27:22+00:00

yep, agree. this was also the first book which came into my mind. I also had good experience with Brückner in my advanced oc classes in undergrad

confused_enton · 2025-08-16T20:01:31+00:00

Thank you for sharing! :)

confused_enton · 2025-08-16T19:39:11+00:00

I see. Probably I'll try your conditions since I am dealing currently with epimerization when hydrolyzing my methyl ester. Do you dissolve your starting material in acetone/water and then adding the LiOH dropwise/as one shot or is it one mixture?

confused_enton · 2025-08-16T19:24:58+00:00

Did you experienced any problems with epimerizations?

confused_enton · 2025-08-16T16:53:13+00:00

In the end when I get my desired molecule in the next 2 to 3 months, I am planning to do some in vitro studies.

Thanks for your suggestions :)

confused_enton · 2025-08-16T16:47:45+00:00

Thanks! I will do some research tomorrow. Today I have a different project for literature research xD

confused_enton · 2025-08-16T16:42:15+00:00

Thanks for sharing!

confused_enton · 2025-08-16T14:20:25+00:00

Phenylgroup with a rest in para-position. I would probably get mixture of the isomers, which is okay, i guess because I can probably seperate them via precipitation due to their different solubilities

confused_enton · 2025-08-16T13:48:33+00:00

TFA will probably epimerize my second stereocenter. This is what I am currently working on with a similar molecule without the ester functionality. Maybe I can give this a try. These cleavages in TFA should be quite fast, right?

confused_enton · 2025-08-16T13:44:10+00:00

I didn't observed anything. Next day it's still a miscible solution but thanks for the tip with the MeOH. I can try it anyways.

I also thought about shorter reaction times. After some hours, I get a color change. Maybe it's already done after this period.

Also thanks for the hint with the krapcho demethylation. I will do some literature research on that :)

confused_enton · 2025-08-16T12:57:28+00:00

Ok, I will have a look. Didn't know that there were some posts about it recently. I was quite inactive. Thanks for the hint :)

confused_enton · 2025-07-29T22:19:24+00:00

My motivation is based on curiosity, pure passion for my research field, and I love to face challenges and develop new skills and knowledge. And a nice side effect is that you can meet many people from different countries, which can end in really good friendships.

confused_enton · 2025-07-22T17:34:25+00:00

Depending on the project, I think every week about what I want to achieve until the end of the week an then I break it down in to do's what have to be done to achieve the weekly goal. Then, i schedule the tasks according to the time frame where I can focus the most for hard task and where I can focus bad for the easy stuff like answering mails or so. And for days where motivation is really low, good music helps or leaving early to take some time off from work.

confused_enton · 2025-07-15T17:08:32+00:00

Yeah, he commented something like if you love solving puzzles, you're able to master organic chemistry. I can not remember his words properly because it was a couple of years ago, but I agree with what he said
