The development of efficient methods for accessing fluorinated functional groups is desirable. Herein, we report a two-step method that utilizes catalytic Cu for the decarboxylative trifluoromethylation of propargyl bromodifluoroacetates. This protocol affords a mixture of propargyl trifluoromethanes and trifluoromethyl allenes.

greenhouse experiment was conducted to assess the response of wheat to tank mixture of herbicides with insecticide and manure in ferdowsi university of mashhad, iran. the experiment consisted of 8 treatments: 1- tribenuron methyl (15-20 g ha-1) + clodinafop propargyl (0.8 l ha-1) 2- tribenuron methyl + clodinafop propargyl + fenitrotion (1.2 l ha-1) + librel (1 kg ha-1) 3- tribenuron methyl + c...

A valuable pharmacophore, the 2-aminoimidazole moiety, can be accessed with a variety of substitution patterns through an addition-hydroamination-isomerization sequence (see scheme; R(1),R(4),R(5)=alkyl; R(3)=alkyl, aryl; R(2)=H, alkyl, aryl). The synthesis of the propargyl cyanamide precursors through a three-component coupling enables the preparation of this important heterocyclic core struct...

The enantioselective silver-catalyzed propargylation of N-sulfonylketimines is described. This reaction proceeds in high yield and excellent enantiomeric ratio and is compatible with a wide variety of diaryl- and alkylketimines. Synthetic transformations of homopropargylic products via enyne ring-closing metathesis, Sonogashira cross-coupling, and reduction reactions proceed with high stereoche...

the reduction of herbicide applications is a main research priority in recent years for herbicide reducing the risk of side-effects and costs from herbicides. therefore to predicting additive, synergism or antagonism effects mesosulfuron + iodosulfuron and clodinafop-propargyl two herbicides mixture on wild oat with isobole curvatures, greenhouse experimental in completely randomized design wit...

adjutants' ability in enhancing the performance of herbicides is a major priority in adjuvant research. to identify an appropriate adjuvant for pinoxaden and clodinafop propargyl herbicides against littleseed canarygrass (phalaris minor retz.), common wild oat (avena fatua l.) and ryegrass (lolium temulentum l.), three separate experiments were conducted under greenhouse conditions. in all...

various adjuvants carry out different functions depending on the herbicides types and the target species. outdoor pot experiments were conducted to evaluate the effects of three post-emergence herbicides, namely, clodinafop-propargyl, haloxyfop-p-methyl, and difenzoquat-methyl-sulfate, as influenced by two adjuvants, on wild oat (avena ludoviciana durieu.) control. the study was carried out at ...

Aspergillus flavus was isolated from the soil field cultivated with wheat crop (Triticum astevium L.), which treated Topik EC 100 (Clodinafop-propargyl) herbicide in Al-Fuhud city, southeast of Thi-Qar Governorate-Iraq. samples were collected at a depth (0-15) cm for period 17 weeks, and fungus by dilution method, pH, electrical conductivity, organic matter texture measured. results showed that...
