Protocols for the synthesis of the bulky polyfluorinated triarylboranes 2,6‐(C6F5)2C6F3B(C6F5)2 (1), 2,6‐(C6F5)2C6F3B[3,5‐(CF3)2C6H3] (2), 2,4,6‐(C6F5)3C6H2B(C6F5)2 (3), 2,4,6‐(C6F5)3C6H2B[3,5‐(CF3)2C6H3] (4) were developed. All boranes are water tolerant and according to the Gutmann‐Beckett method, 1–3 display Lewis acidities larger than that of the prominent B(C6F5)3.
The synthesis of 2-BrC 6 H 4 SbPh 2 (1) and the serendipitous formation 2-(2'-BrC 6 H 4)C 6 H 4 SbPh 2 (2) are reported. Compounds 1 and 2 were characterized in solution by NMR spectroscopy and their identity was confirmed by high-resolution mass spectrometry. The molecular structures of both compounds were determined by single-crystal X-ray diffraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
