Myristticaceous plants characteristically contain a rare class of natural products called diarylnonanoids which have nine carbon units between two aromatic rings.

Catalytic synthesis of diphenylethylane with solid superacid SO_4~(2-)/TiO_2 doped rare-earth lon La~(3+);

5% and selectivity to diphenylethylane of 78.

The synthesis of diphenylethylane with xylol and styrene as reactants and solid superacid SO_4~(2-)/TiO_2 doped with rare earth metal ions as catalyst has been studied.

Studies on Diarylheptanoids from Qinglongyi

Results Five diarylheptanoids were isolated from the bark of Myrica rubra and identified as myricanol(1),11-O-methoxymyricanol(2),5-deoxymyricanone(3),myricanone(4) and 12-hydroxymyricanon.

This thesis describes natural diarylheptanoids from distribution, bioactivity, biosynthesis and synthesis and focuses on the synthesis of several diarylheptanoids.

Synthesis of diphenylethane catalyzed by the new clay solid acid;

The yield of diphenylethane under such conditions was about 85%, which was 15% higher than the yield when using sulfuric acid as catalyst.

The synthesis of diphenylethane over Al-MCM-41 catalyst and its catalytic performance were investigated.
