Coupling of Aryl Halides and Diaryl Diselenides with CuS/Fe

Corrected by: Coupling of Aryl Halides and Diaryl Diselenides with CuS/Fe Synfacts 2011; 2011(03): 0348-0348 DOI: 10.1055/s-0030-1259577 Significance The catalyst system CuS/Fe catalyzed the cross-coupling of aryl halides 1 with ­diaryl diselenides to give the corresponding aryl ­organoselenides 2 in up to 99% yield. For the formation of 2b , the catalyst was reused three times (1 st run: 99% yield, 2 nd run: 98% yield, 3 rd run: 93% yield, 4 th run: 87% yield).
