Preserved Fulltext
By using fresh bamboo condensation raw material, bamboo char sulfonic acid was obtained via sulfuric acid charring and sulfonation, which catalyzed the one-pot three-component synthesis of α-amino phosphonates by condensation of various aromatic aldehydes with aromatic amines and diethyl phosphite. Experimental results have shown that bamboo char sulfonic acids have advantages of high activity, simplicity of operation, wide range of sources and easy recycle.
