, Ethers
+ HX  RX + ROH (SN1/2 via protonering)

Epoxiden
Ringopening onder zure omstandigheden of door nucleofiele aanval (altijd trans)

Aminen
4° N+ OH- Hofmann eliminatie

Amine + H202  RNHOH

Thiolen
Analoog aan ROH, maar kunnen ook RS-Hg-SR

Organometaalverbindingen
Li vervangt X, Mg bindt aan Br (Grignard reagens), reageren als C- (ZB gaat sneller op)
