Abstract
Tris(m-terphenyl-5'-yl)phosphine (2), tetrakis(m-terphenyl-5'-yl)phosphonium bromide (3), sodium tetrakis(m-terphenyl-5'-yl)borate (4), and the phosphonium borate salt 5 of 3 and 4 were synthesized, in the expectation of creating interionic spacings that have unusual electric fields. Characterization was achieved by NMR and FTMS, and, in the case of phosphine 2 and phosphonium bromide 3, via X-ray crystal structure analysis. The electrochemical properties of 2 were different from those of triphenylphosphine, even though the C-P-C bond angles of the two compounds are almost the same.
