摘要：

The cross-coupling reaction of benzoxazole with aryl thiols using the CuI/2,2'-bipyridine complex as a catalyst in DMF at 80 degrees C under oxygen produced the corresponding aryl thioethers in moderate to good yields. The coupling reaction with diaryl disulfide also occurred under similar oxidative conditions. (C) 2009 Elsevier Ltd. All rights reserved.
