“…In this work, solid-state NMR spectroscopy of novel P-Se heterocycles demonstrates the presence not just of intramolecular through-space J couplings, but also of unusual through-space intermolecular couplings that direct the three-dimensional solid-state structure, and use periodic DFT calculations to understand their origin. Two novel selenium phosphorous naphthalenes (1 and 2) were prepared following an adapted route, [17][18] using tertiary phosphines under an oxygen and moisture-free atmosphere, as shown in Scheme 1.…”

Unusual Intermolecular “Through-Space” J Couplings in P–Se Heterocycles

Solid-state NMR spectra of new P-Se heterocycles based on peri-substituted naphthalene motifs show the presence of unusual J couplings between Se and P. These couplings are between atoms in adjacent molecules and occur "through space", rather than through conventional covalent bonds. Experimental measurements are supported by relativistic DFT calculations, which confirm the presence of couplings between nonbonded atoms, and provide information on the pathway of the interaction. This observation improves the understanding of J couplings and offers insight into the factors that affect crystal packing in solids, for future synthetic exploitation.

“…The naphtho[1,8-cd]1,2-dithiole and naphtho[1,8-cd]1,2-diselenole precursors were prepared by literature procedures. [25] The syntheses of 5 and 13 have been reported elsewhere. [17] Naphtho[1,8-cd]1,2-dithiole isopropylphosphine [NapS 2 PiPr] (1) A1m solution of lithium triethylborohydride (superhydride) in THF (11.2 mL, 11.2 mmol) was added dropwise to as olution of naphtho[1,8-cd]1,2-dithiole (1.3 g, 6.8 mmol) in THF (100 mL).…”

A series of P−E‐containing heterocycles (E=chalcogen) with aromatic backbones were synthesised and characterised by single‐crystal and powder XRD, microanalysis and mass spectrometry. Solution‐ and solid‐state 31P and 77Se NMR spectroscopy revealed significant differences between the NMR parameters in solution and in the solid state, related to conformational changes in the molecules. Many compounds were shown to exhibit a number of different polymorphic structures (identified by single‐crystal XRD), although the bulk material studied by solid‐state NMR spectroscopy often contained just one major polymorph. For the unoxidised heterocycles, the presence of weak intermolecular J couplings was also investigated by DFT calculations.

“…These have replaced the less convenient historical syntheses of 94a [80][81][82]. Comparable reactions with elemental selenium and tellurium give the heavier congeners 94b and 94c (Scheme 42) [78,83]. Modification of the method using 1,8-dilithionaphthalene affords mixed chalcogen bridged naphthalenes (Scheme 43).…”

“…In a closely related study, coordination chemistry of a group of diselenolate ligands containing a variety of backbones was investigated [83]. Complexes 115 were obtained by the reaction of in situ generated diselenolates with [PtCl 2 (P(OPh) 3 proximity to the first can be used to modify the reactivity and electronic properties of the overall metallic system thus tailoring it for specific catalytic applications.…”
