Abstract:
A method of synthesizing 2S*, 3R*-6E-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol, one of the active ingredients in the zoapatle plant, is described. The natural product is useful as a utero-evacuant agent.
Abstract:
A process is disclosed for converting aromatic thiols to the corresponding nitroso- or nitro-substituted compounds by treating the thiol compounds with an excess of nitric acid having a HNO3 concentration of 90 to 100 percent. Representative starting compounds are benzenethiols and pyridinethiols which, in addition to the thiol group, are substituted with one or more electronwith-drawing groups such, for example, as chloro, nitro or cyano, among others. The nitroso and nitro compounds produced during the reaction have utility as pesticides and are variously effective as herbicides and in the control of fungi and nematodes as well as of parasites infecting warmblooded animals.
Abstract:
The disclosure is directed to: (a) phosphacycle ligands; (b) catalyst compositions comprising phosphacycle ligands; and (c) methods of using such phosphacycle ligands and catalyst compositions in bond forming reactions.

Abstract:
A method for synthesizing 3,5-dichloroanisole from 1,3,5-trichloro-benzene is proved. The method may comprises: a) the reaction between 1,3,5-trichloro-benzene and a methanolate of an alkaline or alkaline-earth metal in a first solvent chosen from among dimethylsulfoxide and 1,1,3,3-tétramethylurea, b) the precipitation of the product resulting from step a) in a second solvent which is not included among substances considered carcinogenic, mutagenic and/or toxic for reproduction by Regulation (EC) no 1272/2008 of the European Parliament and of the Council of 16 Dec. 2008, then c) the recovery of the precipitate thus obtained. The method may be applied to synthesize 1,3,5-triamino-2,4,6-trinitrobenzene in which 3,5-dichloroanisole is an intermediate product.
