In 2015,Hahn, Lena; Wadepohl, Hubert; Gade, Lutz H. published 《Tetralithiated Tetraazaperopyrene as a Key Intermediate for the Synthesis of Functionalized Derivatives》.Organic Letters published the findings.SDS of cas: 624-73-7 The information in the text is summarized as follows:
A new synthetic approach to core-functionalized tetraazaperopyrenes (TAPP) is reported. In-situ reaction of 4-fold lithiated TAPP with electrophiles results in the formation of various unprecedented TAPP derivatives, which are highly emissive fluorophores, show promising photophys. and electrochem. properties and act as valuable starting materials [e.g., I (formed in situ from tetrabromo precursor) + ClPPh2 → II (46%)]. Thus, lithiation of the TAPP core opens up a facile way for developing new organic materials. In the experiment, the researchers used many compounds, for example, 1,2-Diiodoethane(cas: 624-73-7SDS of cas: 624-73-7)
1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.SDS of cas: 624-73-7
