Claims

The present invention relates to a process for preparing dialkylalkylphosphonite compounds of formula (1) in a glycol ether solvent. The present invention also relates to a process for preparing said compounds of formula (1) in a continuous flow reactor.

1. A process for preparing a dialkylalkylphosphonite compound of formula (1) characterized in that R and R' are independently selected from the substituted or unsubstituted C1 to C8 alkyl or cycloalkyl group, comprising: reacting dialkyl chlorophosphite of formula (3) with a Grignard reagent of formula (4) in a glycol ether solvent; wherein, R, R' are as defined above; and X is selected from Cl, Br, F or I.

5. A process for preparing the dialkylalkylphosphonite compound of formula (1) in a continuous flow reactor, characterized in that R and R' are independently selected from the substituted or unsubstituted C1 to C8 alkyl or cycloalkyl group, comprising: reacting dialkyl chlorophosphite of formula (3) with a Grignard reagent of formula (4) in a glycol ether solvent; wherein, R, R' are as defined above; and X is selected from Cl, Br, F or I.
