(3+2)‐Cyclization Reactions of Unsaturated Phosphonites with Aldehydes and Thioketones

Chemistry – A European Journal, Volume 29, Issue 33, June 13, 2023., 2023
Unsaturated phosphonites are excellent substrates in new (3+2)‐cyclization reactions with aldehydes or thioketones. The cyclisation reactions proceed smoothly at room temperature and lead to the fast formation of the previously inaccessible phosphorus heterocycles 1,3‐oxa‐ and 1,3‐thiaphosphole‐3‐oxides in good to excellent yields.

Highly Selective Separation Intermediate‐Size Anionic Pollutants from Smaller and Larger Analogs via Thermodynamically and Kinetically Cooperative‐Controlled Crystallization

Advanced Science, Volume 8, Issue 6, March 17, 2021., 2021
A novel strategy, cooperatively (thermodynamically and kinetically) controlled crystallization for the highly selective separation of intermediate‐size anionic pollutants, is proposed. Using this strategy, p‐tosylate (Ts−) anion is effectively separated from its analogs of benzenesulfonate (Bs−) and p‐ethylbenzenesulfonate (Es−), and the selectivity is

Photooxidation Coupled Kabachnik–Fields and Bigenelli reactions for Direct Conversion of Benzyl alcohols to α-Amino Phosphonates and Dihydropyrimidones.

Acta Chimica Slovenica, 2020
A tandem one-pot solvent free approach for the direct conversion of benzyl alcohols to α-amino phosphonates and dihydropyrimidones is reported. The method relies on a metal free photo-oxidation of benzyl alcohols to benzaldehydes under UV irradiation ...
