Reaction of the stable digermyne BbtGe GeBbt (Bbt = 2,6-[CH(SiMe3)(2)](2)-4-[C(SiMe3)(3)]-C6H2) with ethylene initially afforded the corresponding 1,2-digermacyclobutene. Depending on the reaction conditions applied, further reaction of this 1,2-digermacyclobutene with ethylene furnished two different reaction products: a 1,4-digermabicyclo[2.2.0]hexane or a bis(germiranyl)ethane. Combined experimental and theoretical results suggested that the 1,4-digermabicyclo[2.2.0]hexane and the bis(germiranyl)ethane are the thermodynamic and kinetic reaction products, respectively. A reaction mechanism in agreement with these results was proposed.

One-Pot Preparation of (NH)-Phenanthridinones and Amide-Functionalized [7]Helicene-like Molecules from Biaryl DicarboxylicAcids

Takuya Murai, Yongning Xing, Mayu Kurokawa, Toshifumi Kuribayashi, Masanori Nikaido, Elghareeb E. Elboray, Shohei Hamada, Yusuke Kobayashi, Takahiro Sasamori, Takeo Kawabata, Takumi Furuta

Summary: A one-pot transformation method has been developed to convert biaryl dicarboxylic acids to (NH)-phenanthridinone derivatives using Curtius rearrangement and subsequent basic hydrolysis. This method is also applicable for preparing optically active amide-functionalized [7]helicene-like molecules. In addition, aza[5]helicene derivatives with a phosphate moiety were obtained as products of the Curtius rearrangement step when chalcogen atoms were present in the substrates. X-ray diffraction analysis revealed that chalcogen-bonding and pnictogen-bonding interactions may contribute to the stabilization of these compounds.

Mitochondria-Targeted Luminescent Organotin(IV) Complexes: Synthesis, Photophysical Characterization, and Live Cell Imaging

Sushree Aradhana Patra, Gurunath Sahu, Pratikshya Das Pattanayak, Takahiro Sasamori, Rupam Dinda

Summary: In this study, five fluorescent organotin(IV) complexes based on ONO donors were successfully synthesized and their photophysical properties were characterized. The results showed that these compounds were easily absorbed by cells and mainly internalized in mitochondria with negligible cytotoxicity at imaging concentration. Additionally, these complexes exhibited high photostability and could be used for long-term real-time tracking of cell organelles. Therefore, this low-toxic organotin-based fluorescent probe has potential applications in imaging mitochondria and tracking changes in their morphology within living cells.

Mridhul R. K. Ramachandran, Philipp C. Brehm, Gregor Schnakenburg, Takahiro Sasamori, Rene T. Boere, Rainer Streubel

Summary: Tricyclic 1,4-dihydro-1,4-phosphasilines 3a,b were synthesized from Si(NR2)(2)-bridged imidazole-2-thione compounds 2a,b. Based on the calculated Frontier Molecular Orbitals (FMOs) of 3b, a possible P-selective P-N bond cleavage reduction could be predicted, and a redox cycle was established using solutions of P-centred anionic derivative K[4b]. The cycle started with the oxidation of K[4b] to form the P-P coupled product 5b, which could be chemically reduced by KC8 to regenerate K[4b].

Summary: This study presents the experimental visualization of the valence-electron-density distribution in benzene and its kinetically stabilized heavier-element analogues, 1,2-disilabenzene and 1,2-digermabenzene. The analysis indicates that the 1,2-disilabenzene and 1,2-digermabenzene have lower aromaticity compared to benzene due to the presence of incompletely delocalized pi electrons on their cyclic conjugation systems.

Selective FRET nano probe based on carbon dots and naphthalimide-isatin for the ratiometric detection of peroxynitrite in drug-induced liver injury

Yueci Wu, Lu-Lu Sun, Hai-Hao Han, Xiao-Peng He, Weiguo Cao, Tony D. James

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.

Strain induced reactivity of cyclic iminoboranes: the (2+2) cycloaddition of a 1H-1,3,2-diazaborepine with ethene

Divanshu Gupta, Ralf Einholz, Holger F. Bettinger

Summary: This study presents the first direct spectroscopic evidence of a cyclic seven-membered iminoborane. Compared to linear amino-iminoboranes, this cyclic iminoborane exhibits weakened bond strength and lower Lewis acidity value. The study suggests that the reduced ring strain of cyclic iminoborane prevents nitrogen fixation but allows facile (2 + 2) cycloaddition reaction with C2H4.
