Metal Ion Catalysis in Nucleophilic Substitution Reactions Promoted by Complexes of Polyether Ligands with Alkali Metal Salts
摘要:
Metal ion effects have been revealed on nucleophilic substitution reactions of n-octyl sulfonates 1-3 promoted by complexes of polyether ligands (PEGs, crown ethers, cryptands) with alkali metal salts MY (M = Li, Na, K; Y = I, Br) in low polarity solvents (chlorobenzene, o-dichlorobenzene, toluene) at 60 degrees C. Rate constants increase, in the order K+ < Na+

Alkylsulfonates (R1-OSO2R2) react with carbon monoxide and alcohol (R3-OH) in the presence of catalytic amounts of Co complex and Nal to afford the corresponding esters (R1-COOR3) in moderate to good yields.
