Recommanded Product: 91-00-9. Recently I am researching about EFFICIENT RECYCLABLE CATALYST; DBN TETRAPHENYLBORATE SALTS; DIRECT AMIDATION; CARBOXYLIC-ACIDS; HIGHLY EFFICIENT; SILICA-GEL; ALCOHOLS; AMINES; PHENOLS; SOLVENT, Saw an article supported by the . Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Ghosh, S; Purkait, A; Jana, CK. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine
An operationally simple and general method for acetylation and acylation of a wide variety of substrates (amines, alcohols, phenols, thiols, and hydrazones) has been reported. Meldrum’s acid and its derivatives have been used as an air-stable, non-volatile, cost-effective, and easy to handle acetylating/acylating agent. Easily separable byproducts (CO2 and acetone) allowed the isolation of analytically pure acetylated products without the requirement of work-up and any chromatography.
