Polymeric Schiff's base chelates and their precursors

Polymeric Schiff's base chelates and their precursors. 6. Covalently polymer bound cobalt chelates from divinylsalenes and their dioxygen binding and catalytic activity. Woehrle, D.; Bohlen, H.; Meyer, G. (Org. Makromol. Chem., Univ. Bremen, Bremen 2800/33, Fed. Rep. Ger.). Polym. Bull. (Berlin), 11(2), 151-8 (English) 1984. CODEN: POBUDR. ISSN: 0170-0839. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The divinyl-Schiff base ligands I [X = (CH2)2, (CH2)3, (CH2)2NH(CH2)2, (CH2)3NH(CH2)3] were synthesized from 2-hydroxy-5-vinylbenzaldehyde [68860-34-4] and diamines. Copolymn. of I with styrene directly leads to covalently polymer bound ligands which form covalently polymer bound chelates with Co(II). The chelates show high activity for the reversible binding of dioxygen under formation of mononuclear superoxo complexes. The chelates exhibit good activities for the oxidn. of 2,6-di-tert-butylphenol [128-39-2].Except for chemicals metioned above, 7440-48-4 and 76372-91-3 are also used. .
