Exposure with 1 atm CO resulted in a reductive coupling process to form cis‐ethendiolate dianion ). Reaction one equivalent PhC≡C−C≡CPh gave 1,4‐diphenyl‐2‐butyne‐1,4‐diyl {[(Tp )Ba] (PhCH−C≡C−CHPh) 4
Mononuclear calcium unsubstituted alkyl complex [(Tp<sup>Ad,iPr</sup>)Ca{(CH<sub>2</sub>)<sub>4</sub>Ph}(THP)], proposed as the catalytic alkene hydrogenation intermediate, was isolated for first time.
Abstract The element nitrogen and nitrogenous compounds are vital to life. synthesis of nitrogen-containing using dinitrogen as the source, not through ammonia, is great interest value but remains a grand challenge. Herein, we describe strategy realize this transformation by combining heterogeneous approach with homogeneous methodology. N2 molecule was first fixed carbon LiH one-pot process, forming Li2CN2 an ‘activated’ source high efficiency. Then subsequent treatments construct organic...
Long-read sequencing holds great potential for characterizing complex microbial communities, yet taxonomic profiling tools designed specifically long reads remain lacking. We introduce Melon, a novel marker-based profiler that capitalizes on the unique attributes of reads. Melon employs two-stage classification scheme to reduce computational time and is equipped with an expectation-maximization-based post-correction module handle ambiguous achieves superior performance compared existing in...
Alkaline electrochemical hydrogen evolution reaction (HER) has been a hot topic in energy catalysis and engineering. Theoretically, intensifying OH adsorption on electrocatalyst is vital for promoting water dissociation thus...
The catalytic regioselective C–H silylation of a wide range alkoxy-substituted benzene derivatives with primary hydrosilane was achieved by the use scorpionate-supported calcium benzyl complex [(TpAd,iPr)Ca(p-CH2C6H4Me)(THP)] (1) (TpAd,iPr = hydrotris(3-adamantyl-5-isopropylpyrazolyl)borate, THP tetrahydropyran) as precatalyst. This protocol offers an atom-efficient and straightforward method for synthesis variety silyl-substituted aromatic ether without hydrogen acceptor free transition...
