From: Copper/iron co-catalyzed alkoxycarbonylation of unactivated alkyl bromides
Ligand effect for this alkoxycarbonylation of unactivated alkyl bromides. Reaction conditions: 2-bromotetradecane (0.5 mmol), CuTc. (5 mol%), L (5 mol%), Fe3(CO)12 (5 mol%), NaOMe (0.75 mmol), CO (40 bar), MeOH/toluene (0.5/2 mL), 24 h. The yields (%) of esters are based on 2-bromotetradecane. The yields (%) of esters and conversion (%) of 2-bromotetradecane are determined by GC analysis using hexadecane as the internal standard
