How glow sticks are made
Glow sticks contain chemical substances, which emit light when they are mixed together. This phenomenon is called chemiluminescence. Glow sticks are known under the product names such as Cyalume and ...
Hiyama Cross Coupling
General Characteristics The cross coupling reaction between aryl halides/triflates and organosilicon reagents (organosilanes) is generally called the Hiyama coupling. Most organosilicon reagents are ...
Ether Synthesis by Acetal Reduction
General Characteristics The reduction of the oxonium cations generated by acidic treatment of acetals is a way to synthesize ethers. Triethylsilane (Et3SiH) is a reducing agent that is stable under ...
Arndt-Eistert Synthesis
General Characteristics The Wolff rearrangement of diazoketones prepared from acid chlorides and diazomethane is especially called the Arndt-Estert synthesis, which is an effective way of one-carbon ...
