The reaction of different functionalised organolithium intermediates 1 – 3 with several electrophilic olefins 6 (2-cyclopentenone, 2-cyclohexenone, methyl vinyl ketone, benzylideneacetone, benzylideneacetophenone and ethyl acrylate) in the presence of copper(I) salts (bromide and iodide) in THF at ...
Write a balenced ionic equation for the reaction occurring when:(a) the addition of metallic aluminum to a copper(II) nitrate solution results in the precipitation of copper metal and the formation of aluminum ions in solution.(b) metallic copper is added to a dilute solution of nitric acid...
Copper(I) catalysts are usually ineffective on the other hand Pd(II) catalysts are quite effective in promoting intramolecular sp2 C–H functionalization (C–S bond formation). Herein, we have developed a ligand assisted Pd(II) catalyzed C–S bond formation via C–H activation from arylthiourea...
2. Water Soluble FluxWater soluble flux is also known as organic acid (OA) flux. It is is primarily composed of organic materials other than rosin or resin. Water-soluble flux provides good soldering results because they have good flux activity. They have good wetting action (ability to ...
