[sudden badger]

don't wanna work out the entire thing

G batayo pls

🥀

[neon elm]

oh man what is this

chota hi hai

[sudden badger]

ngl I overate and abhi sir ghoom raha hai

discord kholte hi

ye notif

aa gaya

[kindred berry]

benzaldehyde

[sudden badger]

make a cyanohydrin

next

[kindred berry]

not acc to key

it somehow does benzoin condensation

without ethanol

[sudden badger]

huh

KCN hmmm
but then there is nothing else in the solution

how

do they make anything except a cyanohydrin

[silk canopy]

[sudden badger]

but your thing mentioned "neat KCN"

[kindred berry]

fr

[sudden badger]

what is O

[kindred berry]

benzene

[sudden badger]

so this actually feels like some sort of a reduction

and tf is ZnCl3

?

[kindred berry]

😭

ask allen ppl

[manic gull]

What the hell is ZnCl3?

[kindred berry]

idk either

[neon elm]

Salt

[manic gull]

Zn3+?

[slender rose]

ZnCl2 is a weak lewis acid catalyst, similar to the ones we use in Fredielcraft reactions

Like AlCl3

if I had to guess, I would say the mechanism is very similar to acylation.
Instead of ending up with a carbonyl cation, you should get H3C - C(+) =N which can substitute into the benzene ring

looks probable. The catalysts are very similar to acylation reaction's.

Ag and heat just precipitates out white AgI from the CH3-I
So you have acetylene formed from that step, which undergoes cyclisation and aromatisation

to O

HCl and HgCl2 can hydrate actylene to form acetaldehyde, kucherov reaction.

and again, cyanohydrin formation in G to K

@kindred berry does this make sense

[kindred berry]

its ZnCl3 tho

[slender rose]

type

ZnCl3-

exists

[kindred berry]

ooo

valid

[mellow dome]

Why isnt this forming vinyl chloride which goes polymerisation to make PVC

[neon elm]

i found some

weird named

condensation

which can have Zn salt to be used as catalyst

[slender rose]

sorry

[kindred berry]

arey yeh toh padha hai

ill brb after lunch

[neon elm]

Kya hua boss? 🙃

[kindred berry]

meine jo knoevenagel padhi hai usmein amine ya pyridine use hota hai

[manic gull]

Knoevenagel uses it.

Just no ZnCl3.

[nocturne folio]

we good? @kindred berry

[kindred berry]

Yeag
