Alpha-R alkoxy p-chlorobenzyl phosphonic acid monoester

The invention discloses alpha-R alkoxy p-chlorobenzyl phosphonic acid monoester. The structural formula of the alpha-R alkoxy p-chlorobenzyl phosphonic acid monoester is shown in the specification, wherein R1 is selected from-(C5-C8) alkyl, -(C3-C8) cycloalkyl or -(C2-C8) alkenyl; R2 is selected from alkyl of -(C1-C5) or cycloalkyl of -(C3-C6); and M is H or alkali metal ions or alkaline earth metal ions or organic ammonium cations. The alpha-R alkoxy p-chlorobenzyl phosphonic acid monoester is a brand-new intermediate alpha-R alkoxy p-chlorobenzyl phosphonic acid monoester used for preparing 1-(4-chlorphenyl)-2-cyclopropyl-1-acetone, the preparation method of the intermediate is provided, the purity of the alpha-R alkoxy p-chlorobenzyl phosphonic acid monoester prepared through the method can reach 98.9%, the yield can reach 94.7%, when the compound is used for preparing 1-(4-chlorphenyl)-2-cyclopropyl-1-acetone, the purity and the yield are greatly improved, and the quality of cyproconazole is further improved.
