C–H and H–H activation at a di-titanium centre

C-H and H-H activation at a di-titanium centre.

The reaction of the bis(pentalene)dititanium complex Ti2(μ:η5,η5-Pn†)2 (Pn† = C8H4(1,4-SiiPr3)2) with the N-heterocyclic carbene 1,3,4,5-tetramethylimidazol-2-ylidene results in intramolecular C-H activation of one of the iPr methyl groups of a Pn† ligand and formation of a "tucked-in" bridging hydride complex. The "tuck-in" process is reversed by the addition of hydrogen, which yields a dihydr...

A look on trauma code activation in a major trauma centre in UAE: a descriptive study

Background:Trauma is considered to be a major cause of morbidity and mortality all over the world. This descriptive study has an emphasize on the epidemiology, mechanism and patterns of trauma, with a consideration of why trauma code was activated, and the imaging results in regard to the severity of the trauma. Method: A descriptive study was conducted in Al Ain Hospital over the year of...

Unusual carbamate-directed CH-activation at an annulated ferrocenophane framework.

The tetrahydroazepine-annulated [3]ferrocenophane carbamate (4) was synthesized by two different linear routes starting from the readily available α-dimethylamino[3]ferrocenophane-ortho-carbaldehyde rac-6. The carbamate directed lithiation of 4 resulted in a selective attack at a (Cp)C-H bond at the higher substituted "lower" [3]ferrocenophane Cp-ring to eventually yield the respective ester (1...

Di-Higgs final states augMT2ed – Selecting hh events at the high luminosity LHC

hh j j production at the LHC

The search for di-Higgs production at the LHC in order to set limits on the Higgs trilinear coupling and constraints on new physics is one of the main motivations for the LHC high-luminosity phase. Recent experimental analyses suggest that such analyses will only be successful if information from a range of channels is included. We therefore investigate di-Higgs production in association with t...
