The Mass Spectra of Lithiomethyltrimethylsilane and Lithium t-Butoxide

Optical Properties of Vanadium Pentoxide Deposited by ALD

“…It has previously been speculated if true ALD growth of lithium compounds is impossible due to the single positive charge of lithium and this causes lithium to exist as complexes with only one ligand [148], if true this would also extend to other alkali metals. This is however not the case as shown for example for LiO t Bu which exist as a hexamer [153,154,169] in the gas phase and LiHMDS exists as a dimer in the gas phase [152], as described previously.…”

“…LiHMDS is a dimer in the gas phase and liquid phase and a trimer in the solid state [151,152]. LiO t Bu is reported to exist as a hexamer in the solid state [153] and in gas phase [154,155]. Li(thd) on the other hand is reported to be tetrameric in the gas phase [156].…”

Control of Lithium-t-Butoxide Addition during Chemical Vapour Deposition of Li-Doped Diamond Films by Optical Emission Spectroscopy

“…It sublimes easily at temperatures above 100 C. The vapour pressure was determined to 0.13 mbar at 120 C [16]. LiOC 4 H 9 molecules are aggregated in the solid and also in the gas phase in hexamer units [17]. In the present work the Li compound was heated in a separate chamber in order to establish a defined vapour pressure.…”

Anionic polymerization of (meth)acrylic monomers: anionic polymerization of tert‐butyl methacrylate in toluene

“…The usual behaviour of organolithium compounds is, indeed, to be increasingly more associated in solvents of decreasing polarity. 17 Therefore the picture that emerges is that only part of the oligomers formed at the very early stage of polymerization are able to exceed a critical size and to be converted into longer chains that grow in a living manner, whereas all the other oligomers suffer from pseudo-termination (Scheme 2). As a result, concentration of the living chains [PtBMA À , Li ] remains constant, and there is no evidence of termination reactions.…”
