Metal organic phosphate open framework materials (III), (V), and (VII) are investigated as hybrid cathode materials for lithium ion batteries.

The systematic phytochemical investigation of Abies spectabilis afforded the 3 new compounds (I)-(III) and 69 known compounds.

Abiespiroside A (1), a unique sesquiterpenoid spirolactone with a 6/6/5 ring system, was isolated from Abies delavayi Franch. The structure was established as (1R,5R,6R,7S,9R)-6,9α-epoxy-9,15-bisabolanolide-5-O-β-D-glucopyranoside by extensive analysis of various spectroscopic data and further confirmation by the single-crystal X-ray diffraction. It showed potent inhibitory activity against the production of nitric oxide in RAW264.7 macrophages stimulated by lipopolysaccharides.

p -Toluenesulfonyl radical can be generated from sodium p -toluenesulfinate in aqueous acetic acid or formic acid. Sulfonyl radical mediating reaction of 5-aryl sbustituted alkenes with sodium p -toluenesulfinate/copper(II) acetate gave p -toluenesulfonylmethyl substituted naphthalene and isoquinoline derivatives. This reaction proceeded much faster in aqueous formic acid than in aqueous acetic acid. The cyclization mode (Ar 2 -6 vs Ar 1 -5) of the 5-phenyl-1-butly radical is strongly dependent on the geometry of the tether of the radical intermediate.
