Copper-catalyzed trifluoromethylation of organic zinc reagents with an electrophilic trifluoromethylating reagent

A copper-catalyzed trifluoromethylation of aryl, vinyl and alkyl zinc reagents with Togni's reagent was described. Mechanistic studies indicated that the aryl group is initially transferred from the zinc reagent to hypervalent iodine to form a tri-substituted hypervalent iodine intermediate. Consequent reductive-elimination via a concerted bond-forming step and/or radical pathway from this intermediate generates the trifluoromethylated arenes.

Herbicidal pyridine compounds

Herbicidal 3- and/or 5-halogenomethyl-pyrid-2-yloxyphenoxy compounds and processes for making and using the same. Intermediates for making these compounds and their preparation are also disclosed. Thus, for example, 2-chloro-5-trichloromethylpyridine is prepared by a liquid phase chlorination of 3-methylpyridine under the influence of ultra violet light.

Herbicidal mono- or di-substituted-2-pyridinyloxy-phenoxy-lower-alkane-carbamates

Herbicidal pyridine compounds of the formula (I): STR1 wherein Z may be halogen, or a fluorine- or chlorine-substituted alkyl group of 1 to 4 carbon atoms, and Y may be hydrogen, halogen, or a fluorine- or chlorine-substituted alkyl group of 1 to 4 carbon atoms; X may be an OH group or an acyloxy group; a halogen atom; an amino group, a mono- or di-alkyl amino group, or an alkanoylamido group; an alkoxy group optionally substituted by hydroxy or alkoxy; or a mercapto group, an alkylthio group, or a phenylthio group. The invention also provides herbicidal compositions containing the compounds, and processes for making the compounds.
