Metal Ion Catalysis in Nucleophilic Substitution Reactions Promoted by Complexes of Polyether Ligands with Alkali Metal Salts

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 deg C.Rate constants increase, in the order K(+) M(+)) assists the departure of the leaving group ("electrophilic catalysis").

STEREODESIGN OF CROWN ETHERS. I. SYNTHESIS AND (13)C NMR STUDY OF TRANS- CYCLOHEXANOCROWN ETHERS

A series of trans-cyclohexanocrown ethers were synthesized by the intermolecular cyclization of polyethylene glycol trans-2-hydroxycyclohexyl ethers with the ditosyl derivatives of polyethylene glycols.A complete assignment of the signals in the (13)C NMR spectra was made for the obtained compounds.
