Green synthesis of 1,3,5-triazine derivatives using a sonochemical protocol

Abstract

1,3,5-triazine derivatives are useful compounds with potential applications in various branches of chemical industry, including pharmaceutical chemistry, cosmetic chemistry, photochemistry, and organic chemistry. Due to the growing environmental requirements on conducting efficient, economical, and safe syntheses, development of new methods for synthesizing organic compounds is highly desirable. In this publication, we present a protocol for the synthesis of 1,3,5-triazine derivatives using a sonochemical approach. In as little as 5 min, it is possible to obtain most of the investigated compounds with a yield of over 75%. An undeniable advantage of this method, besides its short time, is the use of water as the solvent. Furthermore, we provide examples that the sonochemical method may be more versatile than the competing microwave method. Analysis conducted using the DOZNTM 2.0 tool revealed that in terms of the 12 principles of green chemistry, the developed sonochemical method is 13 times “greener” than the classical one. Additionally, it has been demonstrated that the investigated molecules are attractive for their application as drug-like compounds.
