Schisandrin(1)under the Ritter reaction conditions(conc.H<sub>2</sub>SO<sub>4</sub>/CH<sub>3</sub>CN)gave trace amounts of the expected acetamidoderivatives(2a,2b).Th
The concept of pseudo orbital has been proposed, which includes the interactions of all the orbitals and extends the applicable limit of Fukui’s frontier orbit
On-line dissolution of solid metal sample can be carried outby electrolysis under the control of flow injection analyzer(FIA),andthe dissolved sample can be tra
