  Reaction of the lithium salt of N,N′,N″-triisopropylguanidinate with Fe(III) or Fe(II) halides led to isolation of the new species [(PriN)2C(HNPri)]2FeCl (1) and [μ-η2-(PriN)2C(HNPri)] 2Fe[η2-(PriN)2C(HNPr i)]}2 (2); attempted alkylation of 1 with 1 equiv. of a variety of reagents produced 2; the reaction of 2 with LiCH2SiMe3 resulted in a coupling reaction between the two bridging ligands to yield [(μ-η2∶η2-(PriN)2 C)2NPri)]Fe[η2-(PrNi )2C(HNPri)]}2.

  N,N²,N³-三异丙基胍锂盐与Fe(III)或Fe(II)卤化物的反应导致分离出新的物种[(PriN)2C(HNPri)]2FeCl 1和[μ-N2-(PriN)2C(HNPri)]2Fe[N2-(PriN)2C(HNPr1)]}2；尝试用1当量的各种试剂对1进行烷基化反应，得到2；2与LiCH2SiMe3反应，导致两个桥连配体之间的偶联反应，得到[(μ-N2-μ-N2-(PriN)2C)2NPri)]Fe[N2-(PrNi1)2C(HNPri)]}2。

  Copper (1) guanidinate dimers were generated by a salt metathesis route and structurally characterized. The guanidinates differed from the known amidinate dimers because of a large torsion of the dimer ring. This had a direct effect on their thermal chemistry. The thermal reactivity was investigated by several methods, including a novel temperature-resolved, gas-phase method that was monitored by mass spectrometry. The copper guanidinates underwent carbodiimide deinsertion to produce copper metal at temperatures between 225 -and 250 degrees C in the gas phase and at 125 degrees C in solution. The amidinate investigated also showed copper deposition at 190 degrees C in the gas phase, and 135 degrees C in solution, but without carbodiimide deinsertion. The guanidinate compounds deposited crystalline copper at 225 degrees C in a simple chemical vapor deposition experiment.

  A family of new mixed-ligand titanium guanidinate compounds was synthesized as potential atomic layer deposition precursors, and the surface chemistry on silica of a promising candidate (Cp2Ti[((NPr)-Pr-i)(2)CN(H)Pr-i]) was explored. Generally, these compounds have very good thermal stability with onsets of volatility between 127 and 168 degrees C, with melting points generally ranging from 147 to 165 degrees C. The reactivity of [(PrN)-Pr-i(H)C((NPr)-Pr-i)(2)]TiCp2 was studied with high surface area silica between 180 and 330 degrees C. The surface reactivity was found to differ if the silica was preheated to 350 or 900 degrees C; this was attributed to the hydroxyl nucleation site density of the silica, which is known to vary with the temperature. The surface reaction products were characterized by solid-state NMR, and these agreed well with a calculated model. When the silica was pretreated to 350 degrees C, the precursor appeared to chemisorb primarily through the loss of a Cp ligand, while with a 900 degrees C pretreatment, the chemisorption occurred primarily through a loss of the guanidinate ligand. The adsorption enthalpies to silica were calculated for the different surface species.
