Abstract

The synthesis and magnetic properties of poly (2, 2, 4, 4-tetramethyl-N-yloxy-1, 4-dihydro-2H- 3, 1-benzoxazine-6, 8-diyl-1, 3-phenylene)(4) are described. Polyradical 4 was prepared by the Pd-catalyzed cross-coupling reaction of 6, 8-dibromo-2, 2, 4, 4-tetramethyl-1, 4-dihydro- 2H-3, 1-benzoxazine and bis (trimethylene) 1, 3-phenylenediboronate, followed by oxidation with m-chloroperoxybenzoic acid. The number average molecular weights of 4 ...
