New possibilities for the synthesis of reactive functional aminopolysilanes using azide pathway [PDF]
Memoirs of the Scientific Sections of the Romanian Academy, 2014 Two new reaction frameworks with high stereospecificity and high yields are described. Azidopolysilanes offers multiple options for obtaining aminopolysilanes, either by reducing the azido group using the Staudinger technique or by Huisgen 1,3 ...

Biological and Pharmaceutical Bulletin, 1995 Alkyl azides showed mutagenicity for S. typhimurium TA100 strain with S9 mix. However, no significant activity was observed for TA98 either with or without S9 mix or for TA100 without S9 mix. On the other hand, 3-azido-1,2-propanediol showed the enantioselective activity regardless of S9 mix.

Tuning the magnetic ground state of a novel tetranuclear Nickel(II) molecular complex by high magnetic fields [PDF]
, 2006 Electron spin resonance and magnetization data in magnetic fields up to 55 T of a novel multicenter paramagnetic molecular complex [L_2Ni_4(N_3)(O_2C Ada)_4](Cl O_4) are reported. In this compound, four Ni centers each having a spin S = 1 are coupled in a single molecule via bridging ligands (including a \mu_4-azide) which provide paths for magnetic ...

Novel Rubidium Poly-Nitrogen Materials at High Pressure [PDF]
arXiv, 2017 First-principles crystal structure search is performed to predict novel rubidium poly-nitrogen materials at high pressure by varying the stoichiometry, i. e. relative quantities of the constituent rubidium and nitrogen atoms. Three compounds of high nitrogen content, RbN_{5}, RbN_{2}, and Rb_{4}N_{6}, are discovered. Rubidium pentazolate (RbN5) becomes

Temperature‐ and pH‐Responsive Polymeric Photocatalysts for Enhanced Control and Recovery
Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022 Stimuli‐responsive photocatalytic materials have emerged that are not only able to efficiently catalyze reactions but can use external stimuli to modulate their physical properties. This technique has been used to control the reactivity of a photocatalytic material turning it on/off. Moreover, photocatalytic materials have been synthesized which can be
