1,2,3-Triazole N(2)-coordinated C-O coupling: Access to ortho aryloxyl 1,4-diaryl 1,2,3-triazoles
YAOWEN LIU FEN ZHAO HAOHUA ZHOU KAI XIE YUBO JIANG
CuI-catalyzed selective Ullmann C–O coupling of 1,4-disubstituted 1,2,3-triazole bromides with phenols were achieved through the coordination of N(2) atom. The ortho C–Br bond in N(1) aryl can be selectively coupled with phenols, while other C–Br bonds remain inert, generating ortho aryloxyl 1,4-diaryl1,2,3-triazoles.

XINYUAN MA WEIGEN DU WEI LIU YAOWEN LIU TIEBO XIAO YUBO JIANG
A facile and efficient method for direct C–H formylation of phenolated 1,4-disubstituted 1,2,3-triazoles using DMSO as the formyl source has been developed. The reaction proceeded smoothly under metal-free conditions with good functional group tolerance and high selectivity co-controlled by the triazole ring and hydroxyl group.
