Synthese von oligomeren und polymeren Monosacchariden durch Aldol‐Gruppentransfer‐Polymerisation

Abstract: I] a) E. S . Huyser: Free Radical Chain Reactions. Wiley. New York 1970. S. 121 M. Ramaiah, Terrahedron 43 (1987 3541. [3] 0.03 mol/L des Alkens 2 in Cyclohexan wurden bei 300-450°C und 200 bar 2 min in einem Hochdruck/Hochtemperatur-Stromungsreaktor umgeseht 141. Die Radikalkette wird durch molekillinduriene Homolyse gestanet [4b]. Die Produktlbsungen wurden kapillargaschromatographisch analysiert. Die Produkte wurden durch unabhangige Synthese und/oder GC/MS identifiziert. 141 a) P. K6I1, J. 0. Metzger. An… Show more
