Compounds with Ligands Bonded by Five Carbon Atoms,ted at -196°C. The mixture is heated for 1 h at 50°C, and the product is vapor-transferred as a mixture of a white solid and colorless crystals. Be(C.H.)D is prepared analogously from Be(C.H.)BD.. The reaction of Be(C.H.)BH. with a large excess of N(CH.). or P(CH.). at room temperature gave Be(C.H.)作者: 字的誤用 時(shí)間: 2025-3-22 02:50
Compounds of Unknown Structure,on Be.R.H. (R = CH., C.H.) or Be.(C.H.).H [1 to 5]. There is little evidence about their constitution. Whereas the latter example is discussed as a single compound in the literature [4, 5], solutions of Be.R.H. may contain many species in complex equilibria [2].

Book 1987Latest editions compounds. The compounds of this element are, in principle, at least as interesting and intriguing to scientists as those of other metals in the Periodic Table. No doubt the main reason for the apparent ban of all experimental organoberyllium chemistry is to be found in the established, and allege作者: 懶鬼才會(huì)衰弱 時(shí)間: 2025-3-22 19:33 作者: Vo2-Max 時(shí)間: 2025-3-22 21:39

Book 1987Latest edition covers the literature com- pletely to the end of 1986 and includes most of the references up to mid-1987. This Gmelin volume is different from all other volumes of the series on organometallic compounds in that it is dedicated to an area of research which has virtually come to a complete standstill作者: ECG769 時(shí)間: 2025-3-26 08:22 作者: 表兩個(gè) 時(shí)間: 2025-3-26 10:56
