The ruthenium‐catalyzed dehydrogenation of alcohols in the presence of N,N'‐diisopropylcarbodiimide in toluene under neutral conditions proceeded smoothly to give corresponding carbonylcompounds in good to excellent yields with good functional group tolerance. This is the first report for the use of carbodiimide as a hydrogen acceptor for dehydrogenative oxidation of alcohols. Kinetic analysis for

lithium guanidinate [Li(Me3Si)2NC(NiPr)2}], obtained in situ from the amide [LiN(SiMe3)2(Et2O)] and 1,3-diisopropylcarbodiimide in THF, yields the bis(guanidinate) “ate” complex [Lu(Me3Si)2NC(NiPr)2}2(μ-Cl)2Li(THF)2] (1). The alkyllutetium derivative [Lu(Me3Si)2NC(NiPr)2}2(CH2SiMe3)] (2) was synthesized by a metathesis reaction of 1 with LiCH2SiMe3 in toluene. The treatment of 2 with an equimolar amount

A series of new N-alkyl functionalised 6- and 7-membered expandedring N-heterocyclic carbene (NHC) pro-ligands 3–6 and their corresponding complexes of rhodium(I) and iridium(I), [M(NHC)(COD)Cl] 7–14 and [M(NHC)(CO)2Cl] 15–22 are described. The complexes have been characterised by 1H and 13C1H} NMR, mass spectrometry, IR and X-ray diffraction. It is noted from X-ray diffraction studies that the N-alkyl

the structure [(η(2) -L)Ca(μ-η(2) :η(2) -L)(μ-η(2) :η(1) -L)Ca(η(2) -L)]. These amidinate complexes showed unprecedentedly high volatility as compared to the widely employed and commercially available Ca(II) precursor, [Ca3 (tmhd)6 ]. In CaS ALD with 1 and H2 S, the ALD window was approximately two times wider and lower in temperature by about 150 °C than previously reported with [Ca3 (tmhd)6 ] and H2
