1-Fenüül-2-nitropeen (P2NP) videosüntees bensaldehüüdist ja nitroetaanist. Henry reaktsioon.

[HIGGS BOSSON]

Probleemid nitroetaaniga algasid Euroopas juba 2007. aastal, seejärel kehtestasid kõik riigid järk-järgult piirangud sellele väärtuslikule reaktiivile. Ja nüüd on kaks võimalust: otsida tarnijaid riikides, kus on nõrk seadusandlus ja arenenud keemiatööstus, näiteks Bangladeshis, või sünteesida iseseisvalt, mille metoodika me oleme välja pakkunud.

Millega saab nitroetaani asendada või sünteesida?

 

[Kvadprime]

You can find methods of syntes nitroethane in another thread

I have aniline as a base - what yeilds can it give?

 

[G.Patton]

Try and figure out. Share us your research data. In theory, it's quite weak base and it would be not enough to eliminate -OH group.

 

[Kvadprime]

ok, I'll definitely write how everything went... I'm still waiting for my new labware to arrive

Thx

 

[rampage]

has anyone done the microwave version of this synthesis, curious as to the outcome?

 

[William D.]

This is an effective method. I irradiate at maximum power in short time intervals so that the mixture does not have time to boil.

 

[rampage]

that is the key, stopping the irradiation just prior or as soon as you see 1 tiny bubble rise up, did this method with very good success, simple but very effective. would be very interested if there's other synths that can be done using the microwave??
