The regiospecific ω-bromination of 2-trichloroacetylcycloalkanones
摘要:
Six novel omega-brominated-2-trichloroacetylcycloalkanones were regiospecifically obtained in reactions from four 2-trichloroacetyleycloalkanones and bromine. H-1 and C-13 NMR data reveal that omega-brominated beta-diketones are predominantly in keto-keto form. (C) 2007 Elsevier Ltd. All rights reserved.
