WebApr 2, 2003 · Anionic λ4-phosphinines 3 and 4 were synthesized via the reaction of the corresponding λ3-phosphinines 1 and 2 with MeLi. The X-ray structure of [3][Li(thf)2] is reported and shows the η5-coordination of the Li cation to the five carbon atoms of the phosphacyclohexadienyl moiety. Cryptated species [3][Li[2.2.2]] and [4][Li(thf)4] were also … WebThe geometry and electronic structure of several phosphinine-ether macrocycles were investigated at semiempirical level. The calculated geometries are in good agreement with experimental data. Compared to phosphinine, the coordinative abilities of phosphinineether macrocycles based on energy considerations suggest a little lowered π acceptor …
