Recently rare earth elements have been used to catalyze alkyl–alkyl cross coupling and other organic transformations. Herein we report the synthesis and characterization of a tris(amido) Lu complex, 1-Lu, analogous to the Sc and Y rare earth complexes known to participate in these transformations. Complex 1-Lu displays similar solid state structural properties as its Group 3 congeners, but EPR spectroscopy reveals differing behavior. 1-Lu also was found to break the trends of reaction rates related to oxidation potential and is able to catalyze an alkyl–alkyl cross-coupling reaction faster than the Sc and Y analogs. The complex 1-Lu was also demonstrated to participate in two-electron redox catalysis.

Purpose Concurrent alcohol and drug use has been found to increase the risk of injury for many recreational activities. The purpose of this study was to determine the relationship between substance use and craniofacial injury in a population of patients experiencing skateboard- and scooter-related trauma. Methods We report a cross-sectional study of patients reported to the National Electronic Injury Surveillance System (NEISS) from January 1, 2019, to December 31, 2020, in the United States. Patients were included in our study if they were evaluated in the emergency department (ED) for a skateboard- or scooter-related injury. The primary outcome was craniofacial injury. The secondary outcome was hospitalization. Results There were over 5396 total patients who presented to a NEISS-participating ED after skateboard- or scooter-related trauma during the study period. There were 1136 patients with a craniofacial injury (primary endpoint), and patients under the influence of alcohol or drugs had greater odds of experiencing a craniofacial injury than those not under the influence (odds ratio [OR]: 4.16, 95% confidence interval [CI]: 3.24-5.32, P < .0001). Four hundred-thirty patients were hospitalized (secondary endpoint), and patients under the influence had greater odds of being hospitalized than those not under the influence (OR: 2.83, 95% CI: 2.04-3.91, P < .0001). Conclusions Alcohol and drug use while skateboarding or scootering drastically increases the likelihood of craniofacial injury and subsequent hospitalization and should be avoided whenever possible. The importance of wearing a helmet while operating these devices cannot be overstated.
