In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR)3, a central phosphate molecule with alkyl or aromatic substituents. They can be considered as esters of phosphoric acid. Like most functional … Zobacz więcej Alcoholysis of POCl3 Phosphorus oxychloride reacts readily with alcohols to give organophosphates. This is the dominate industrial route and is responsible for almost all organophosphate … Zobacz więcej Guanitoxin is a naturally occurring organophosphate produced by cyanobacteria.
