WebOrthophosphate is also called “phosphate” and “reactive phosphorus” because it is very easy to make it bond with other positive elements and compounds since it has three “extra” electrons that strongly want to bond with protons. Methods. The two common colorimetric methods of measuring . orthophosphate are: WebThe aryne phosphate reaction is a powerful tool to – depending on the perspective – (oligo)phosphorylate arenes or arylate (oligo-cyclo)phosphates. Based on Kobayashi-type o-silylaryltriflates, the aryne phosphate reaction enables rapid entry into a broad spectrum of arylated products, like monophosphates, diphosphates, phosphodiesters and ...
