Bromide substitution in lithium borohydride, LiBH4–LiBr [PDF]
International Journal of Hydrogen Energy, 2011 By means of in situ synchrotron radiation powder X-ray diffraction, powder neutron diffraction, attenuated total reflectance infrared spectroscopy, differential scanning calorimetry and the Sieverts techniques we have investigated how anion substitution in the LiBH4eLiBr system leads to changes in the structural, physical, chemical and hydrogen storage

Space cooling using geothermal single‐effect water/lithium bromide absorption chiller
Energy Science & Engineering, 2021 This research is proposed to fully investigate the performance of a single‐effect water/lithium bromide absorption chiller driven by geothermal energy. Since absorption cycles are considered as low‐grade energy cycles, this innovative idea of rejecting ...

Enantioselective Access to Trifluoromethylated Spirocyclopropyl Heterocycles
Advanced Science, EarlyView.We report a rhodium‐catalyzed asymmetric [2+1] spirocyclopropanation of methylene azacycles with trifluoromethyl carbenes in situ derived from fluoroalkyl triftosylhydrazones. ABSTRACT Chiral spirocyclopropyl heterocycles have emerged as privileged three‐dimensional structural motifs in medicinal chemistry.

Dual Nickel/Photoredox‐Catalyzed Regio‐ and Enantioselective Alkenylation of Epoxides
Advanced Science, EarlyView.Ni/photoredox‐catalyzed stereoconvergent cross‐electrophile coupling of racemic epoxides with alkenyl bromides is described, affording β‐alkenyl products with up to 95% ee, excellent E‐selectivity, and complete regiocontrol. These versatile intermediates enable diverse chiral synthons; mechanistic studies suggest a halide ring‐opening followed by ...

Palladium‐Catalyzed Cross‐Coupling of Transiently Stable Heterocyclic Organolithiums
Angewandte Chemie, EarlyView.Fast coupling outcompetes organolithium decomposition. Catalyst benchmarking enables transient pyridyl, quinolyl, indazolyl, and related organolithiums to participate in the Murahashi coupling, while continuous‐flow generation extends the approach to reagents too unstable for conventional batch handling.
