A new method for the synthesis of Cl-BODIPYs from F-BODIPYs is reported, merely requiring treatment of the F-BODIPY with boron trichloride. Cl-BODIPYs are exploited as synthetic intermediates generated in situ for the overall conversion of F-BODIPYs to O- and C-BODIPYs in high overall yields using a mild one-pot procedure. This route enables F-BODIPYs to be transformed into derivatives that are...

The synthesis and spectroscopic characterisation of six bis(5-X-pyridine-2-yl)isophthalamides (X = H, F, Br, Cl, I, NO2) are reported, together with five crystal structure analyses (for X F to I). isophthalamides span a range conformations as syn/anti (H-DIP; I-DIP), anti/anti- (F-DIP; Br-DIP) both present in ratio 2:1 Cl-DIP. essentially isostructural F-DIP Br-DIP molecules (using strong amide...

The photochemical deactivation process of HCFC-133a (C2H2F3Cl) was investigated by computing excited-state properties with a number of single-reference methods, including coupled cluster to approximated second order (CC2), algebraic diagrammatic construction to second order (ADC(2)), and time-dependent density functional theory (TDDFT). Excited states calculated with these methods, especially T...

LetW (A) andWe(A) be the joint numerical range and the joint essential numerical range of an m-tuple of self-adjoint operators A = (A1, . . . , Am) acting on an infinite dimensional Hilbert space, respectively. In this paper, it is shown that We(A) is always convex and admits many equivalent formulations. In particular, for any fixed i ∈ {1, . . . ,m}, We(A) can be obtained as the intersection ...

The SnIV atom in the title diorganotin compound, [Sn(C7H6F)2Cl2(C2H6OS)2], is located on a centre of inversion, resulting in the C2Cl2O2 donor set having an all-trans disposition of like atoms. The coordination geometry approximates an octa-hedron. The crystal features C-H⋯F, C-H⋯Cl and C-H⋯π inter-actions, giving rise to a three-dimensional network. The respective influences of the Cl⋯H/H⋯Cl a...

Platinum-organic Compounds, Syntheses, Reductive Elimination, Activation Parameters The Compounds cw-[Pt(PPh3)2(4-X-C6H4)2] [X = F, Cl, CF3, OCH3, N(CH3)2] and cis[Pt(PPh3)2(4-X-C6H4)(Y-C6H4)] [X = F/Y = 3 Cl, 4-C1, 3-CH30, 4 -CH 3 0; X = CF3/Y = 3-F, 4-F] have been synthesized and studied thermally with respect to the reductive elimination of disubstituted biphenyls. Activation parameters A H+...

The uranyl tetrachloride dianion (UO(2)Cl(4)(2-)) is observed in the gas phase using electrospray ionization and investigated by photoelectron spectroscopy and relativistic quantum chemical calculations. Photoelectron spectra of UO(2)Cl(4)(2-) are obtained at various photon energies and congested spectral features are observed. The free UO(2)Cl(4)(2-) dianion is found to be highly stable with a...

OBJECTIVES This study was designed to separate focal from atypical macro-re-entrant atrial tachycardia (AT) on the electrocardiogram (ECG). BACKGROUND Focal AT often cannot be distinguished from macro-re-entrant AT until the time of electrophysiology study (EPS). We hypothesized that quantitative ECG metrics should separate focal AT, using its short activation relative to tachycardia cycle le...
