Synthesis and Structure of P73 (Tri(hypersilyl)heptaphosphanortricyclane),.). groups and that two enantiomers are present in crystals grown from benzene. The .P NMR spectrum shows the complex splitting pattern of an A. spin system. .P chemical shifts and .P, .P one-bond and two-bond coupling constants have been calculated by numerical simulation of the spectrum.粗鄙的人 发表于 2025-4-1 06:31:28

Reactions of a Cyclotrisilane with Chalcogen Transfer Reagents,Treatment of hexa-.-butylcyclotrisilane (.) with Et.PTe afforded the telluratrisiletane . in high yield. Irradiation of . in the presence of phenyl isothiocyanate furnished the l,4-dithia-2,5-disilacyclohexane-3,6-diimine ring compound .. The structures of . and . were determined by X-ray crystallography.buoyant 发表于 2025-4-1 21:26:08
Sr,Mg,Li,Si,, die erste ,-Phase mit einer Si,-Kette,The investigation of the quarternary systems ./Mg/Li/Si (. Ca, Sr, Ba) led to a new . compound Sr.Mg.Li.Si. with an interesting allylic Si. unit. The electronic configuration was analyzed with the help of quantum chemical calculations.墙壁 发表于 2025-4-2 01:50:31
