N,N′-bis-Boc aryl hydrazines underwent Cu(I) catalyzed couplings with aryl halides to provide N,N′-bis-Boc diaryl hydrazines. The resulting N,N′-bis-Boc diaryl hydrazines are readily oxidized to the azobenzenes in the presence of Cu(I) and a base. A prolo
New approaches to side-chain fluorinated bioimidazoles: 4-alkynylimidazoles as substrates for fluorination

, p. 105 - 110 (2007/10/03)
4-Alkynylimidazoles have been prepared and their behavior as substrates for "FBr" addition (NBS+Et3N·3HF) have been studied. Facile Markownikov addition to ethylnylimidazole 2 gave fluorobromoolefin 9a, a potential synthon for the 2-imidazolyl-
