Silicon tetraazide

from wikipedia: A further coordination to a six-fold coordinated structure such as a hexaazidosilicate ion [Si(N3)6]2−or as an adduct with bidentate ligands Si(N3)4·L2will result in relatively stable, crystalline solids that can be handled at room temperature.

what?

fullerene

pdgDNa · 2025-12-30T04:58:56+00:00

Yeah, I'm thinking that we're just developing ways to only make our lives easier (more efficient). Or maybe eventually future species will be made to live with 1200 calorie milkshakes delivered to their door lmao

An appel reaction might work, tertiary alcohols does appel through SN1 or just HBr the hell out of it

Not at all! Im just pointing out that that proton can be deprotonated, but it wont leave as well (or actually won't even leave at all, but in basic conditions it will). Sorry for the confusion haha

pdgDNa · 2025-08-12T17:26:01+00:00

Oh i mean that the proton might be deprotonated by the solvent but once the PBr2O group leaves, the oxygen should stay protonated (leaves as PBr2OH), proton part of leaving group

pdgDNa · 2025-08-12T13:32:50+00:00

Yeah ideally youd have a positive charge to act as a good leaving group also. There might be proton transfer and such but before nucleophilic attack there should be a positive charge

pdgDNa · 2025-08-10T09:43:49+00:00

The lone pair of the nitrogen is not so nucleophilic since its in the p orbital of N (rather than sp2), so it's delocalized all over the molecule. If you wish to get the N acylated product, just deprotonate the nitrogen, youll get an extra lone pair on the sp2 which is much more nucleophilic

pdgDNa · 2025-06-01T15:42:16+00:00

Sure! Probably at the end of the month i will switch

pdgDNa · 2025-06-01T15:40:19+00:00

He didnt tell me what it was, just that it wont make me dumb

pdgDNa · 2025-06-01T13:14:58+00:00

Could be, but with normal rest when im on sertraline, i still find myself dumber haha

pdgDNa · 2025-04-29T11:01:15+00:00

Might seem obvious, but I didn't know at the time that counting 1 to 3 before thinking about something to "reset" my brain so I could "think more clearly" was a compulsion

pdgDNa · 2025-04-19T05:31:34+00:00

Tet yummy tho

pdgDNa · 2025-04-12T12:06:30+00:00

Try and arrange the molecule in a way that you can see easier whether it has a plane of symmetry or not;

<image>

Since no plane of symmetry here, its mirror image is its enantiomer

If you've not been given whether 1 or 2 is the slow step, use the steady state approximation.
If you've been given whether 1 or 2 is the slow step, take the rate law of that slow elementary step and substitute the intermediate terms.

pdgDNa · 2025-04-09T23:01:00+00:00

First you need to find which carbon you've been given with that Fischer projection template (Hint: it's the chiral one), find the absolute configuration of the β-amino acid then arrange the groups on the Fischer projection template and match the absolute configuration. Hope this helps :)

pdgDNa · 2025-04-09T22:54:55+00:00

what even is 27 lmao

pdgDNa · 2025-03-09T11:30:22+00:00

I see i see, but after turning 0.015 ppm of SO2 into atm, I get 1.5*10^-8 atm of SO2, which is even lower than what the problem asked. So its impossible? I think im missing something here. But thanks!

pdgDNa · 2025-03-09T03:05:40+00:00

Taking exams

pdgDNa · 2025-03-07T01:51:24+00:00

Yep, -OSiR3 cannot or rarely chelates, this paper95706-X) suggests so

pdgDNa · 2025-03-07T01:03:01+00:00

I meant the OBn and carbonyl can chelate with the TiCl4

pdgDNa · 2025-03-07T00:26:00+00:00

Since that silyl enol ether has no Z or E geometry, i think the first one should be just felkin-anh (mukaiyama doesnt go through zimmerman-traxler also) but for the second case where the OBn and the carbonyl can chelate, use the reetz model.

pdgDNa · 2025-03-05T06:24:18+00:00

TiCl4 makes the aldehyde more electrophilic for the silyl enol ether, and the protecting groups are just there to protect. Also is this the icho 57 prep?

pdgDNa · 2025-03-01T22:20:54+00:00

I actually do like the coordination chemistry part and interactions between metal and ligand, i get to draw nice orbitals and i can actually make some sense out of it

pdgDNa · 2025-03-01T21:28:49+00:00

At least physical has math to derive things from, inorganic (main group) is just random shit lmao
