We reported a novel simplified synthetic procedure for the preparation of monosubstituted piperazine derivatives which can now be easily prepared in a one-pot-one-step way from a protonated piperazine with no need of introduction of a protecting grou

We report a novel sophisticated synthetic method for preparation of monosubstituted piperazine derivatives, which can now be easily prepared in a one-pot-one-step way from a free piperazine with no need of introduction of a protecting group bringing
Mobile positioning is recognised to be one of the most promising new sources of data for the production of fast and cost-effective statistics regarding population and mobility. Considerable interes...

Pivaloylacetonitrile is a crucial intermediate for the synthesis of the isoxazole skeleton of the selective herbicide isouron and for the construction of inhibitors of p38 MAP kinase based on pyrazolyl ureas. The current method of synthesis is based

Pinewood nematodes (Bursaphelenchus xylophilus) and Asian longhorned beetles (Anoplophora glabripennis) are the primary regulated pests for packaging wood and timber in the EU, while the house longhorned beetle (Hylotrupes bajulus) is the most import

The Ag-Cu bimetallic colloidal nanoparticles (NPs) were prepared by solvothermal synthesis from metalloorganic precursors in a mixture of organic solvents. The nanoparticles were characterized by dynamic light scattering (DLS) and small angle X-ray s

Three new multi-step one-pot processes for high-yielding cyclohexanecarbonitrile synthesis starting from cyclohexanone were developed for industrial application. In contrast to the current synthetic process, all of the processes described were design
