Boron Difluoride beta-Diketonates:IV.~1 Reaction of p-Alkyl-substituted Benzoylacetonates with N-Bromosuccinimide

摘要

Bromination of p-alkyl-substituted boron difluoride and chromium(III) benzoylacetonates with N-bromosuccinimide was studied.It was found that that the boron difluoride complexes are selectively brominated by the alkyl radical,whereas chromium toluoylacetonate,by the central carbon atom of the chelate ring.
