TL;DR: In this paper, die Auswirkungen der Substitution von Schwefel durch Sauerstoff an der 2-Position diskutiert. Butt et al.
Abstract: Synthese und Eigenschaften von Metall(II)- und/oder Metall(III)-bis Chelaten des 1,3-Dithiol-2-on-4,5-dithiolats (dmid) vom Typ An[M(dmid)2] (A = Bu4N+, Ph4As+; M = Zn, Cd, Hg, Cu, Ni, Pd, Au, Fe; n = 1, 2) werden beschrieben. Anhand der IR-, 13C-NMR-, EPR-Spektren und Cyclovoltammogramme dieser Chelate und analoger Chelate des 1,3-Dithiol-2-thion-4,5-dithiolats (dmit) sowie EHT-Rechnungen werden die Auswirkungen der Substitution von Schwefel durch Sauerstoff an der 2-Position diskutiert. Die Rontgenkristallstrukturanalyse von Bu4N[Ni(dmid)2] ergab die Raumgruppe P1 mit a = 11,925(2), b = 12,095(2), c = 12,164(2) A, α = 97,88(1), β = 109,82(1), γ = 97,21(2)° und Z = 2.

TL;DR: In this paper, vanadium oxytrichloride was used to induce a new C-C bond formation in naphthalene derivatives, but it failed to induce photochemically a new bond.
Abstract: Oxidative dimerizations of some naphthalene derivatives were studied. With vanadium oxytrichloride either a new C-C bond formation occured or the reagent caused chlorination of the ring. Attempts to induce photochemically a new C-C bond failed.

TL;DR: The crystal and molecular structure of bis(tetraphenylarsonium) bis(maleonitriledithiolato)tellurate(II), a new tellurium(II) compound containing dithiolene ligands, and the single-crystal e.s. spectra of the system [AsPh4]2[63Cu/Te(mnt)2] are reported as discussed by the authors.
Abstract: The crystal and molecular structure of bis(tetraphenylarsonium) bis(maleonitriledithiolato)tellurate(II), a new tellurium(II) compound containing dithiolene ligands, and the single-crystal e.s.r. spectra of the system [AsPh4]2[63Cu/Te(mnt)2] are reported. [AsPh4]2[Te(mnt)2] crystallises in the triclinic space group P, with a= 10.211 (2), b= 14.460(2)A, c = 18.583(3)A, α = 105.95(2), β = 95.60(2), γ = 77.67(2)°, and Z = 2; R= 0.047 for 7749 observed reflections. The tellurium atoms have trapezoid planar co-ordination with Te–S bond distances of 2.501(1), 2.482(2), 2.971(2), and 3.104(2) A. In the single-crystal e.s.r. spectra the signals of two Cu sites with somewhat different spin-Hamiltonian parameter sets are observed. The and the 63Cu hyperfine tensors are rhombic symmetric. The planar [Cu(mnt)2]2– anions are considerably distorted but do not adopt the structure of the tellurium host.
