WebOct 17, 2024 · It is known that (2-oxopropyl)phosphonates have high CH acidity and, as expected, should be effective in classical cyclization reactions of 1,3-dicarbonyl compounds. Despite this, the use of dialkyl (2-oxopropyl)-phosphonates in the synthesis of phosphorylated heterocycles is surprisingly little studied. Only 32 works have been … Alkyl phosphates belong to a group of organic compounds called organophosphates. They are esters of phosphoric acid H3PO4 and corresponding alcohol. For example, the formula of methyl phosphate is CH3-H2PO4, dimethyl phosphate – (CH3)2HPO4 and trimethyl phosphate – (CH3)3PO4. … See more In Dialkyl phosphates, two of the hydrogens in phosphoric acid are replaced by alkyl groups, e.g. dimethyl phosphate – (CH3)2HPO4 Agricultural use Dialkyl phosphates … See more In Trialkyl phosphates, all three hydrogens in phosphoric acid are replaced by alkyl groups, e.g. trimethyl phosphate – (CH3)3PO4.
