NettetRT @Francois_Gabbai: Congrats to Jiliang and Eli for the synthesis of a large-bite P/π+ ambiphilic ligand that supports gold-bound anion-π+ interactions. Also reported is the … Nettet1. jan. 1997 · The peak of the fluoroborate HOBF3 7 slowly decreased in the absence of fluoride ion (see Table 4) to give a peak at -- 150.5 pprn cor- responding to BF~- 8. The polyborate and the fluorine-containing prod- ucts A, B, C and D formed during the deboronation, but significantly not in the initial stages, were not identified.
