Arten und Bauformen von Stellventilen,Several σ-bonded organoiron derivatives have been reported. Some of them have not been properly identified. The latter appear hereafter, followed by other, better described compounds, which include aliphatic, alicyclic, aromatic, aliphatic-sulfur bridged and acetylenic derivatives.佛刊 发表于 2025-3-25 18:48:07

https://doi.org/10.1007/978-3-663-07606-3Alkyliridium compounds of the general formula XX’ were prepared from carbonylbis(tert-phosphine)iridium chloride, Cl, through the reaction with alkyl halides used in large excess, followed by the precipitation with pentane.lethal 发表于 2025-3-26 00:43:47
Including Lanthanides and ActinidesTriethylscandium and triethylttrium etherates were prepared from ScCl. and YCl., respectively, by the reaction with EtMgBr (317). Attempts to duplicate the results were unsuccessful (2).PHONE 发表于 2025-3-26 05:33:32
Molybdenum CompoundsPotassium trialkynyltricarbonylmolybdate complexes, of the general formula K., were prepared from Mo(CO).(NH.). by the reaction with potassium acetylides, KC≡CR, in liquid ammonia. The compounds were obtained in the form of yellow-green to orange crystals, diamagnetic, non-explosive, but sensitive to air and moisture.江湖郎中 发表于 2025-3-26 09:52:57
