abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
The synthesis of a new yellow fluorescent 4-(2-methylamino)-ethyloxy-N-PAMAM-1,8-naphthalimide from zero generation has been described. The chemical structure of synthesized dendrimers was confirmed using FT-IR, 1HNMR and DSC techniques. The new materials are comprised of a 1,8-naphthalimide fluorophore having a substituent at C-4 position. The synthesized compounds (P2 and P3) were ...
