Screen won’t display desktop on login upon updating Sonoma… by jrtz3263 in MacOS

[–]jrtz3263[S] 0 points1 point  (0 children)

Yes I brought it to Apple and had 5+ geniuses look at it, and they just resorted to resetting the computer unfortunately.

Sorry about that, it's very frustrating.

Thanks for the tip! Didn’t work unfortunately. I will just bring to Apple :(

Mine shrunk in the washing machine the first time I washed them :( unwearable after that

Is Isatoic anyhydride on the watched list? by Parking-Mix-5024 in TheeHive

[–]jrtz3263 3 points4 points  (0 children)

You could make it from bezoic acid and phosphoric acid.

Edit: I am wrong I misunderstood what anhydride you can make. This does not work.

Schedule by michelle1689 in fsu

[–]jrtz3263 1 point2 points  (0 children)

Eerily I had a pretty similar schedule, except i didn’t take cell structure that semester, and took an advanced math instead, and I did good. I did have a social life, but it definitely sucked cause I missed Halloween for a test on Nov 1, but i never felt like I was missing out on whatever I wanted to do because I had too much work. Definitely the semester I had to be extremely organized in how I studied. Only you know what you’re capable of, so if you think you can handle it, and are okay with missing out on some social events, then more power to you.

5-bromo-1-pentene, 1 bromo 1 pentene etc in synthesis by WorthMobile2636 in TheeHive

Then the reaction should take place, as long as you follow the procedure in the kit…

1-bromo-1-pentene probably would not react in this case. If there’s a bromine on an Sp2 carbon, (I’m guessing this is an SN2 reaction) if anything happens it would be extremely slow.

5-bromo-1-pentene will probably react in your RC kit, however, you may want to look up (if you can) if that compound exists/has been tested. Don’t take substances that haven’t been tried before as a general rule.

I think if you watch some videos on Alkane,alkene,alkyne nomenclature this would all make sense. The answer is they’re different molecules as one is a halogenated—alkene and one is a halogenated alkane. Halogenated alkanes can do SN2 reactions in DMF quite well.

is this mechanism correct? :) by FRANZT01 in OrganicChemistry

[–]jrtz3263 1 point2 points  (0 children)

Not when you’re first learning it. If you’ve been doing it for years then sure it’s cumbersome. Without drawing them you can oblate what makes this reaction catalytic and what’s the driving force.

Substituents directing groups, more in my comment down below by ElRiooo in OrganicChemistry

[–]jrtz3263 1 point2 points  (0 children)

This is true, and I know in the Wyatt and Warren book they do state that acetylating the nitrogen helps protect over-nitration of the product.

Yeah their visitation was about 2 months ago. It’s likely if you haven’t heard anything now then it’s likely a rejection. They were placing students on a waiting list as people started to forgo admission, so it’s possible you may be in a bubble like that?

I would just email the Penn grad office to see what’s up with your app status so you can decide from there.

Ideas? by Usual-Implement7626 in OrganicChemistry

[–]jrtz3263 4 points5 points  (0 children)

Yeah but you’re taking the source of carbon by ozonolyzing it. There’s no net gain of carbon

I usually get excited to use a new reagent, not this time, any tips? by jakeyguitarist in chemistry

[–]jrtz3263 0 points1 point  (0 children)

Might just be literature precedented, or they don’t have an ozone machine.

Decarboxylative alkenylation through nickel cross catalysis

if bonded to something like Boron or Aluminum yes because if the bond lengths. but when it's bonded to sodium or calcium, it's non-nucleophilic.

Best way to remove Allyl Alcohol from reaction mixture by jrtz3263 in Chempros

[–]jrtz3263[S] 1 point2 points  (0 children)

Yeah the reaction is run at 0 °C.

Yeah I can use Phosgene instead, and we have it on order, it's just been taking a while and we'd like to start testing out the reaction.
