In 2019,Journal of Organic Chemistry included an article by Perez-Caaveiro, Cristina; Oliva, Maria Moreno; Lopez Navarrete, Juan T.; Perez Sestelo, Jose; Martinez, M. Montserrat; Sarandeses, Luis A.. Application In Synthesis of 4,6-Dichloropyrimidine. The article was titled 《Synthesis of D-A-A and D-A-D Pyrimidine π-Systems Using Triorganoindium Reagents: Optical, Vibrational, and Electrochemical Studies》. The information in the text is summarized as follows:
A series of donor-acceptor-acceptor (D-A-A) and donor-acceptor-donor (D-A-D) systems based on a pyrimidine π-spacer with various substituents at the C-2 position has been successfully prepared The synthesis involved site-selective palladium cross-coupling reactions of chloropyrimidines with triorganoindium reagents and proceed in good yields and with atom economy. 4-(N,N-Diphenylamino)phenyl was chosen as the donor group and thien-2-yl dicyanovinylene as the acceptor one. The optical, vibrational, electrochem., and d. functional theory (DFT) calculations of these mol. systems were analyzed, and exptl. values show the important role of the substituents at the C-2 position of the pyrimidine with stronger electron accepting ability, absorption in a wide range of UV/vis, acceptable fluorescence lifetime, and effective intramol. charge transfer (ICT) properties. The ICT was observed in both series by the bathochromic shift on increasing the polarity of the solvent. In addition, DFT calculations found lower lowest unoccupied MOs of D-A-A mols. that suggest good electron ejection and transportation, being good properties for their application in various organic optoelectronic devices. After reading the article, we found that the author used 4,6-Dichloropyrimidine(cas: 1193-21-1Application In Synthesis of 4,6-Dichloropyrimidine)
4,6-Dichloropyrimidine(cas: 1193-21-1) is a member of organic chlorides. Organic chloride content in crude oil can be detected through specialized laboratory analysis. Care and attention are essential while sampling and testing.Application In Synthesis of 4,6-Dichloropyrimidine
