  Bis(cyclopentadienyl) zirconium(IV) amides as possible precursors for low pressure CVD and plasma-enhanced ALD

  摘要：

  Low pressure chemical vapour deposition (LPCVD) of [ZrCp2(NMe2)(2)] (1), [ZrCp2(eta(2)-MeNCH2CH2NMe)] (2), [ZrCp2'(NMe2)(2)] (3) and [ZrCp2'(NEt2)(2)] (4) (Cp = eta(5)-cyclopentadienyl, Cp' = eta(5)-monomethylcyclopentadienyl), onto glass substrates at 600 degrees C, afforded highly reflective and adhesive films of zirconium carbide and amorphous carbon. Powder XRD indicated that the films were largely amorphous, although small, broad peaks accounting for ZrC and ZrO2 were present, suggesting that the remaining carbon was due to amorphous deposits from the cyclopentadienyl ligands. SEM images showed an island-growth mechanism with distinct crevices between the concentric nodules. Plasma-enhanced atomic layer deposition (PEALD) of compounds 1 and 2 showed that the precursors were not sufficiently stable or volatile to give a good rate of film growth. (C) 2009 Elsevier B.V.

  Nucleophilic addition to Sn(II) imido cubanes provides a novel route to heteroleptic stannates, as exemplified by the formation of [Sn(NHmmp)(OtBu)2}K·thf]2 (2) and [Sn(MeNCH2CH2NMe)(NHmmp)}Li]∞ (3) from the in situ reactions of the imido Sn(II) cubane [Sn(Nmmp)]4 (1) (mmp = 2-MeO-6-MeC6H3) with tBuOK and [MeN(Li)CH2CH2(Li)NMe]. This pathway demonstrates that Sn(II) imido cubanes can act as synthons for their aza-stannylene constituents, RNSn:.

• Aminosilylation of heterocumulenes and the intramolecular decomposition of their silyl-functionalized adducts

  Heteroorganic amidosilanes are readily obtained by interaction of CO2, CS2 and other heterocumulenes with pentacoordinated diaminosilanes. A comparison is made with the corresponding reactions of tetracoordinated species. Decomposition of these bifunctional organosilanes gives 2-substituted ureido derivatives and base-stabilized low coordinated silicon species, seemingly by a unimolecular thermal beta-elimination.
