Alkylation of malonic acid diethyl ester mechanism?
Hello there, I'm currently doing an organic lab course at university, and we have to do pre-tests for all experiments, including reaction mechanisms. I've managed all of them so far, but I didn't fully understand the alkylation even back then. I can't come up with a sensitive reaction mechanism. Could someone help me? Alkylation is…
How do you open this picture frame?
Hello, I can't open this picture frame anymore. Does anyone know how to do this or have any tips?
Formation mechanism of cumene (2-propylbenzene) to hydroperoxides?
Hello everyone! It's about organic chemistry, which I'm having a lot of trouble with. There's this assignment where autooxidation takes place, and I'm supposed to describe the formation mechanism. However, I don't know where to start or how to continue. There are definitely mistakes in my notes, so it would be really nice and helpful…
Reaction of isopropylbenzene with NBS and carbon tetrachloride?
What do isopropylbenzene, 1 equivalent of N-bromosuccinimide and dibenzoyl peroxide react to in carbon tetrachloride at 70°C, and what is the reaction mechanism? Does radical polymerization occur with NBS and dibenzoyl peroxide, or does carbon tetrachloride somehow react to form a carbene? What approach can be pursued, and how does one arrive at this?
Does anyone have any idea what happened here?
Hello dear community, In the pictures, you can see two of the same product. Both were roasted, bottled, packaged, and stored in the same carton at normal room temperature during the same production period. After two months, I've noticed again that I'm now finding packages that are virtually vacuum-sealed, while others remain normal, as requested….
How to make a cord retractor mechanism?
So it is "a rope" and when you let go of it it retracts itself. It would be best without electronics.
What exactly does the mechanism look like?
I can't imagine how that's supposed to work. And where does the Mn lone pair go after the syn addition?
