A comprehensive I3C-NMR method for the analysis of composition in the most common commercial polyethylene copolymers has been established. The method covers ethene copolymers with propene, butene-1, hexene-1, octene-1, and 4-methyl pentene-1 in the composition range of 1-10 mol %. The chemical shift

A revised structure for hypophyllanthin is proposed on the basis of its 13 C n.m.r. spectrum. 13 C n.m.r. spectra also support the previously proposed structure for nirtetralin and assist in the structural elucidation of a new aryltetralin lignan. Considerable controversy surrounds the structures of
Several metal-sugar conjugates have been prepared. Chelate coordination complexes of copper(I1) and zinc(H) were prepared from salicylaldimine ligands derived from combinations of methyl 3,4,6-tri-0-acetyl-2-amino-2-deoxy-@glucopyranoside or 1,3,4,~tetra-O-acetyl-2-amino-2-deoxy-&D-gluoopyranose and
