Crystalline Half-Parent Vinyl-tetrylenes: Synthesis and Coordination Chemistry.

ABSTRACT: A family of stable, crystalline half-parent vinyl-tetrylenes ^RL(C₂H₃)E: (4-6; ^RL = {[R₂PCH₂Si(ⁱPr)₂](Dipp)N}^-; Dipp = 2,6-ⁱPr₂C₆H₃; R = Ph, Cy) is reported, accessed via a straightforward salt-metathesis pathway, and their electronic properties and initial reactivity explored. All compounds display downfield-shifted signals in both the ¹H and ¹³C NMR spectra for their [C₂H₃] ligand, being most extreme for Pb due to relativistic effects. UV-vis spectra of compounds 4-6 reveal bathochromic shifts relative to the halo-tetrylene derivatives (i.e., ^RLEX; X = Cl, Br), due t
