WebOne option to circumvent this is the combination of the cationic polymerisation of Cl 3 PNSiMe 3 with a second block using a phosphoranimine of the type ClR 2 P N-SiMe 3, resulting in one “tunable” block of [NPCl 2] n, with its wide array of possible substituents, followed by a polyalky/arylphosphazene block. 26 Mar 31, 2024 ·

WebDFT studies suggest that the significant difference in 1JPP couplings observed for [6]+ and [8]+ appears to be related to the electronegativity of the R′ substituents at the phosphoranimine phosphorus center rather than the strength of the donor−acceptor P−P bond, which is slightly weaker in [6]+ relative to that in [8]+, as indicated by ...
