Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. HPLC of Formula: https://www.ambeed.com/products/611-73-4.html, 611-73-4, Name is 2-Oxo-2-phenylacetic acid, SMILES is O=C(O)C(C1=CC=CC=C1)=O, in an article , author is Soltanzadeh, Zahra, once mentioned of 611-73-4.
In this paper, C-N bond formation between 2,3-dihydrophthalazine-1(4H),4-dione (phthalhydrazide) and alpha,beta-unsaturated esters was investigated and a new series of phthalazine derivatives was synthesized using an efficient and simple method under solvent-free conditions. An aza-Michael addition of phthalhydrazide to both acrylic and fumaric esters led to N-monosubstituted phthalhydrazides (as mono-Michael adduct) in the presence of tetrabutylammonium bromide as a high polar media, and 1,4-diaza-bicyclo[2,2,2] octane as an available organic base. In this reaction, the N1,N2-bis-Michael adduct was not observed at all. Also, reactions were performed at 90 degrees C and yields of products were good to excellent.
