An inductively coupled plasma-atomic emission spectrometric method was developed for rapid screening of samples for the dithiocarbamate fungicide mancozeb. The method was based on determining the level of manganese, which forms a major part of the co

Sweroside tetraacetate (2b) has been converted in high yield by osmylation to the epimeric glycols 3 and 4 (R = H) which have been separated. This reaction proceeds with high chemoselectivity for reaction at the vinyl side chain but with low stereose

The oxidation of tetraacetylsecologanin dimethyl acetal (7) by m-chloroperbenzoic acid has been studied and the results have been compared with those obtained when tetraacetylsweroside was oxidized by the same reagent. Complete site selectivity for t

CFCl radicals were generated in a discharge-flow system by the reaction of atomic oxygen with CF2CFCl. Their decay along the flow tube was monitored by fluorescence excited with 386 nm radiation from a dye laser pumped by an N2 laser. Rate coefficien
