## Abstract In the presence of an excess of cysteine, a catalytic amount of a non‐iron transition‐metal ion (Co^2+^, Cu^2+^, Ni^2+^, Ti^4+^, and Mn^2+^) may also induce cleavage of qinghaosu (artemisinin; **1**) to give those end products previously reported for Fe^2+^‐mediated degradation.

## Abstract Lignosulfonic acid doped polyaniline (LIGNO‐PANI) is a water‐dispersible conducting polymer. The incorporation of dopants to achieve higher conductivities in addition to lignosulfonates during the polymerization process results in prohibitively long initiation times. A variety of transi

## Abstract In the reactions of Grignard reagents and __n__‐butyllithium the presence of transition metals and complexing solvents facilitates the formation of anion radicals. High radical concentrations, observable for some days at laboratory temperature, and very well resolved e.s.r. spectra of t
