NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT
α-Aminophosphonates are compounds generally prepared by a three-component synthesis approach using aldehyde or ketone, amine and phosphite as starting materials. Correspondingly, α-hydroxyphosphonates are analogs of α-aminophosphonates prepared mostly from reactions between carbonyl compounds and phosphite...
