Bond Strengths in ChCl3- and ChOCl3- (Ch = S, Se, Te): Experiment and Theory. The strengths of the SeCl2-Cl-, SeOCl2-Cl-, SeBr2-Br-, and TeCl2-Cl- bonds have been measured to be 133 ± 9, 150 ± 10, 110 ± 6, and 170 ± 7 kJ mol-1, r... Lobring,C K.,Hao,....
In such a well-designed process, the oxidation state of the metal in the catalyst would remain the same, thus, making it catalytic in [M] and free of any oxidants for the regeneration of catalyst in many of C–H functionalization reactions11–16. Herein, we wish to report the realization...

Chemical shifts are reported in parts per million (ppm) and are referenced to the solvent peak of CDCl3 as the internal standard (CHCl3: = 7.26 ppm for 1H NMR and 77.16 ppm for 13C NMR). IR spectra were recorded on a Bruker IFS 88 (FT-IR) spectrometer. EI-HRMS were recorded ...
The exponential terms of Equation (1), exp(Δri/c), may be treated as the definition of the bond order. However, other names for this term as well as for similar expressions are often applied in various studies; the bond valence [21] or the bond number [22], for example. The ...
