Mid-infrared signatures of hydroxyl containing water clusters: Infrared laser Stark spectroscopy of OH–H2O and OH(D2O)n (n = 1-3) [PDF]
, 2015 Small water clusters containing a single hydroxyl radical are synthesized in liquid helium droplets. The OH–H2O and OH(D2O)n clusters (n = 1-3) are probed with infrared laser spectroscopy in the vicinity of the hydroxyl radical OH stretch vibration ...

Trivalent Metal Lewis Acids Activate CO<sub>2</sub> in Transfer Hydrogenations. [PDF]
ChemSusChemIndium(III) triflate and other trivalent metal ions catalyst the transfer hydrogenation of CO2 to formate and a series of in situ tandem reactions to yield formamides or azoles. In contrast to previous reports, the reaction proceeds by CO2 activation instead of hydride abstraction from a transfer hydrogenation source. Using γ‐terpinene as a bio‐derived
