Convenient Synthesis of 1,8-Diiodoanthracene and Its Coupling with Thianthrene Boronic Acids
摘要:
1,8-Diiodoanthracene has been prepared from commercially available 1,8-dichloroanthraquinone; it was shown to couple twice under Pd(O)-catalysis, with thianthrene 1- and 2-boronic acids giving 1,8-bis(thianthrenyl)anthracenes.
