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.
Key words
arylations - cations - dendrimers - electric field - bulky salt

5 Attempted X-ray crystal structure analyses of 4 and 5 were unsuccessful, so their diameters and ionic center distances were estimated by PM3 calculation (geometry optimization).
