Dimethyl phosphite reactivity
The Atherton-Todd reaction is a name reaction in organic chemistry, which goes back to the British chemists F. R. Atherton, H. T. Openshaw and A. R. Todd. These described the reaction for the first time in 1945 as a method of converting dialkyl phosphites into dialkyl chlorophosphates. The dialkyl chlorophosphates formed are often too reactive to be isolated, though. For thi… WebConcerning the phosphite component, dimethyl-, di iso propyl- and dibenzyl-phosphites reacted smoothly, delivering the corresponding products in 86–89% yields. Interestingly, tris (2,2,2-trifluoroethyl)phosphite that has two strong electron-withdrawing groups also led to the target product, albeit with a modest yield of 54%.
