Er der andre Lewis-syrer, der kan bruges til at syntetisere 4mmc fra toluen?

Aluminiumchlorid er svært at få fat i for mig.

Ja, for eksempel jernklorid (FeCl3) og zinkklorid (ZnCl3), men reaktionen vil ske langsommere end ved brug af aluminiumklorid.

Er zink- og jernkloriderne vandfri?

Hvilken af de to giver den hurtigste reaktion?

Hvordan syntetiserer man 3-methylpropiophenon?

Ved små synteser er forholdet mellem substraterne det samme 3:1:1,5, eller er der noget, der ændrer sig?

i denne syntese har jeg kun et varmelegeme ballonblander kan jeg ikke bruge et vandbad, og hvor mange grader bør ikke overskrides, når vi tilsætter propinolchlorid

Denne syntese er AlCl3.6H2O, kan jeg bruge det som katalysator?

Jeg er ret sikker på, at det skal være vandfri aluminiumklorid.

Intet vand overhovedet. Problemet er, at man ikke kan tørre aluminiumklorid ved at opvarme det, tror jeg.

Dobbelttjek dog dette

Jeg vil bruge zinkchlorid i denne syntese Hvor mange g zinkchlorid skal jeg bruge i denne syntese?

Samme molære forhold som for AlCl3
