COPPER(I) IODIDE-FACILITATED NUCLEOPHILIC SUBSTITUTIONS OF NONACTIVATED ARYL IODIDES WITH ARENESELENOLATES
Suzuki, Hitomi,Abe, Hisako,Osuka, Atsuhiro
, p. 151 - 152 (2007/10/02)
Nonactivated aryl iodides readily react with areneselenolates, in the presence of copper(I) iodide, in hexamethylphosphoric triamide to produce the corresponding diaryl selenides in good yields.
