7-((5-Bromo-1H-indol-3-yl)(4-methoxyphenyl)methyl)-1,3,5-triaza-7-phosphaadamantan-7-ium Tetrafluoroborate

Abstract

The novel organic salt 7-((5-bromo-1H-indol-3-yl)(4-methoxyphenyl)methyl)1,3,5-triaza-7-phosphaadamantan-7-ium tetrafluoroborate was synthesized from a Lewis acid (LA) and Lewis-base (LB) reaction between 1,3,5-triaza-7-phosphaadmantane (LB) and 5-bromo-3-(4-methoxybenzylidene)-3-H-indol-1-ium tetrafluoroborate (LA). The obtained Lewis acid base adduct, being the title compound, was analyzed and validated by 1H, 13C, 31P, and 19F 1D-NMR-spectroscopy, ESI mass spectrometry, CHN-elemental analysis, and a single crystal X-ray diffraction investigation.
