operational comparison between triphase catalysts derived from la, poly (ethy1ene glycol monomethyl ether), and dibenzo-18-crown8 for cyanide, iodide, and phenoxide displacement on 1-bromooctane. Results presented herein demonstrate that pendant 18- crown-6 offers no special advantage over polyglymes and that polymerized forms of dibenzo- 18-crown-6 have remarkably high activity." Two successful routes to la are outlined in ...
