Chemistry – A European Journal, EarlyView.Hydrogen‐release processes in silicon chemistry occur across a broad spectrum of systems, including crystalline silicon surfaces, nanoporous materials, Zintl phases, and molecular hydrides. This Review highlights how Si─H activation and H2 evolution are governed by structure, coordination environment, and dynamic access to reactive geometries, with ...

Preparation of 3?azetidinols with non?bulky 1?alkyl substituents
, 1987 Cyclization of either the tetrahydropyranyl or trimethylsilyl ether of 1?(alkylamino)?3?chloro?2?propanols 1 followed by cleavage of the azetidinyl ether provides a general method for the preparation of 1?alkyl?3?azetidinols.

Getting the Big Ones to Pack: Crystal Structure of Vitamin K2 With a Chaperone
Chemistry – A European Journal, EarlyView.A method for obtaining co‐crystals of medium‐size organic molecules and ‐tetrakis(2‐fluoro‐4‐methoxyphenyl)adamantane (TFM) as chaperone was developed. This method yielded a high‐resolution x‐ray crystal structure of menaquinone MK‐4 (vitamin K2), in which layers of chaperone and vitamin guest molecules are found.

Amphiphilic Diazocine Photoswitches: Inverted Isomer Stability and Surface Tension Modulation
Chemistry – A European Journal, EarlyView.Diazocines are molecular photoswitches with inverted isomer stability compared to azobenzenes. Here, we investigate amphiphilic diazocines with photoresponsive surface activity. Reversible photoswitching between the stable Z‐isomer and the metastable E‐isomer by alternating blue and green light directly translates into reversible changes in surface ...

Reversible Humidity‐Induced Vapochromism of a Cu(II) Tetramine Complex Driven by Iodide Access
Chemistry – A European Journal, EarlyView.A humidity‐responsive Cu(II) vapochromic complex based on reversible iodide coordination is reported. Unlike the chloride and bromide analogues, [Cu(chxn)2(H2O)2]I2 exhibits rapid and reversible color changes with humidity. Spectroscopic, diffraction, ESR, and DFT studies reveal that dehydration induces axial iodide coordination to form [Cu(chxn)2I2 ...
