v shemi 4 pomeni, da je treba obdelati z zadostno količino amonijevega hidroksida in nasičeno raztopino NH4Cl, dokler se oborina ne raztopi. in koliko uteži je potrebnih?

"Upoštevajte, da uporaba fenil litija namesto fenil magnezijevega bromida povzroči neuspeh prek adicije na nitril in ne izpodrivanja. V prisotnosti Lewisove kisline pa fenillitij izpodrine nitrilno skupino in dobi želeni produkt. Primarni aminoanalogi PCC, kot je N-etilaminocikloheksanekarbonitril, bodo z reakcijo s 3 moli fenilitija proizvedli želene analoge PCP.
"

Kaj to pomeni? Ali je za PCE in druge primarne aminoanaloge z nitrilno metodo in fenillitijem potrebna Lewisova kislina? Ali je potrebna samo za PCP? Katera Lewisova kislina je najboljša?

Ugibam, da je v tem primeru primeren AlCl3

Ali je treba AlCl3 pred nitrilom spustiti v fenillitij? Koliko?

Predvidevam, da gre za katalitično količino.

Zanima me samo, ali ta klorova sol ne bo uničila fenilitija.

Poleg tega teksta ne najdem nobene informacije, kjer bi bilo to potrebno.

Pozdravljeni, tega ne morem zagotoviti, ker s fenilitijem nismo preverjali na ta način.
