A novel route for the synthesis of phosphonate-containing siloxanes by the catalyst-free Kabachnik—Fields reaction
摘要
A new route for the synthesis of siloxanes containing substituents with the phosphonate and amino groups based on the catalyst-free Kabachnik—Fields reaction was developed. The synthesis was accomplished under mild conditions using 3-aminopropylsilanes, cyclic ketones, and diethyl phosphite as the starting materials to give the corresponding 1-(3-silylpropylamino)cycloalkylphosphonates in high yields.
