A synergistic catalytic method combining photoredox catalysis, hydrogen-atom transfer, and proton-reduction catalysis for the dehydrogenative silylation of alkenes was developed. With this approach, a highly concise route to substituted allylsilanes has been achieved under very mild reaction conditions without using oxidants. This transformation features good to excellent yields, operational simplicity, and high atom economy. Based on control experiments, a possible reaction mechanism is proposed.

Compared to the abundance of methodologies accessing 1-substituted and 1,3-disubstuted bicyclo[1.1.1] pentanes (BCPs), the synthetic accessibility of BCPs with substitutions at the methylene position has been limited. Herein, we report a selective synthesis of 1-dialkylamino-2-alkylbicyclo[1.1.1]pentanes from prefunctionalized starting materials. We also achieved further functionalizations of these 1,2-disubstituted BCPs and developed a synthesis of these compounds with minimum necessity of chromatographic purifications starting from 1,3-dichloroacetone. Finally, we also detailed the synthesis of a 1,2,3-trisubstituted BCP analogue.

The catalytic enantioselective synthesis of a-chiral olefins represents a valuable strategy for rapid generation of structural diversity in divergent syntheses of complex targets. Herein, we report a protocol for the dual CuH- and Pd-catalyzed asymmetric Markovnikov hydroalkenylation of vinyl arenes and the anti-Markovnikov hydroalkenylation of unactivated olefins, in which readily available enol triflates can be utilized as alkenyl coupling partners. This method allowed for the synthesis of diverse alpha-chiral olefins, including tri- and tetrasubstituted olefin products, which are challenging to prepare by existing approaches.

Iodine-promoted direct diamination of ,-unsaturated ketone to form two C-N bonds has been developed starting from chalcone and secondary amine. This reaction was performed in THF at 50 degrees C in the presence of I-2 and K2CO3. The protocol is metal-free, operationally simple and carried out under mild conditions, providing an effective new way for directing diamination reactions.

Oxidative carbonylation using CO/O-2 is an attractive strategy to construct carbonyl compounds, but the explosive limit of the gas mixture hampers its application. Now, this safety issue is overcome in the aminocarbonylation of alkynes by replacing the external oxidant O-2 by electrochemistry facilitating a mild and safe reaction. Palladium-catalysed oxidative carbonylation using oxygen as the oxidant is an economical approach; however, the gas mixture of CO and air has an explosive limit of 12.5-74.0% that could hamper extensive application of this process. Herein we report an electrochemical aminocarbonylation of alkynes under atmospheric pressure in an undivided cell without an external oxidant. The transformation has a broad substrate scope (83 examples) that involves primary amines and ammonium salts. Furthermore, mechanistic studies through cyclic voltammetry, in situ infrared and quick-scanning X-ray absorption fine structure spectroscopy reveal the reasons for this protocol proceeding smoothly under electrochemical conditions.

Background: The police attend numerous domestic violence events each year, recording details of these events as both structured (coded) data and unstructured free-text narratives. Abuse types (including physical, psychological, emotional, and financial) conducted by persons of interest (POIs) along with any injuries sustained by victims are typically recorded in long descriptive narratives. Objective: We aimed to determine if an automated text mining method could identify abuse types and any injuries sustained by domestic violence victims in narratives contained in a large police dataset from the New South Wales Police Force. Methods: We used a training set of 200 recorded domestic violence events to design a knowledge-driven approach based on syntactical patterns in the text and then applied this approach to a large set of police reports. Results: Testing our approach on an evaluation set of 100 domestic violence events provided precision values of 90.2% and 85.0% for abuse type and victim injuries, respectively. In a set of 492,393 domestic violence reports, we found 71.32% (351,178) of events with mentions of the abuse type(s) and more than one-third (177,117 events; 35.97%) contained victim injuries. Emotional/verbal abuse (33.46%; 117,488) was the most common abuse type, followed by punching (86,322 events; 24.58%) and property damage (22.27%; 78,203 events). Bruising was the most common form of injury sustained (51,455 events; 29.03%), with cut/abrasion (28.93%; 51,284 events) and red marks/signs (23.71%; 42,038 events) ranking second and third, respectively. Conclusions: The results suggest that text mining can automatically extract information from police-recorded domestic violence events that can support further public health research into domestic violence, such as examining the relationship of abuse types with victim injuries and of gender and abuse types with risk escalation for victims of domestic violence. Potential also exists for this extracted information to be linked to information on the mental health status.

A Cu-catalyzed dearomative amination of simple phenols with O-benzoylhydroxylamines (R’RN-OBz) to synthesize alpha-aminocyclohexa-2,4-dienones is reported. This intermolecular transformation occurs exclusively at the position ortho to the hydroxyl group, providing a convenient method to synthesize the desired products in high yields. The reaction proceeds under mild conditions and tolerates a wide range of functional groups. Mechanistic studies indicate that this transformation proceeds via either (1) a single-electron transfer process involving attack of an N-centered radical onto the phenol or (2) a two-electron pathway involving addition of phenol to an electrophilic Cu-III-amino complex via an inner-sphere process.

A copper-catalyzed regioselective net hydroamination of 1-trifluoromethylalkenes with hydrosilanes and hydroxylamines has been developed. The judicious choice of ligand and additive suppresses the conceivable but undesired beta-F elimination of an alpha-CF3-substituted organocopper intermediate, leading to targeted alpha-trifluoromethylamines in good yields with excellent regioselectivity. Additionally, with an appropriate chiral bisphosphine ligand, the enantioselective reaction is also possible to deliver optically active alpha-trifluoromethylamines of high potential in medicinal and pharmaceutical chemistry.
