Resorcarens la-b (R'=Ph, p-MeOC₆H₄) Were fully alkylated with alkyl iodides or bromides in TEBA/KOH/DMF solid-liquid PTC process with 63-82% yields. whereas the three calix[4]pyrroles 3a-b (2R=2Me, (CH₂)₄(CH₂)₅) were alkylated with alkyl iodides in TBAB/50%NaOH/CH₂Cl₂ liquid-liquid PTC system with lower yields (10-38%).
