- Synthesis and reactivity of dioxazirconacyclohexenes: Development of a zirconium-oxo-mediated alkyne-aldehyde coupling reaction
-
The zirconium-oxo-mediated coupling of an alkyne and an aldehyde for the synthesis of α,β-unsaturated ketones is presented. Each intermediate along the reaction pathway has been fully characterized, and the scope of the alkynes and aldehydes has been explored.

Disclosed are lithium-containing compounds and methods of utilizing the same. The disclosed compounds may be used to deposit alkali metal-containing layers using vapor deposition methods such as chemical vapor deposition or atomic layer deposition. In certain embodiments, the lithium-containing compounds include a ligand and at least one aliphatic group as substituents selected to have greater degrees of freedom than the usual substituent.

- On the Reaction of (Pentamethylcyclopentadienyl)lithium with Halomethanes and Formyl Compounds
-
In view to the synthesis of pentamethylcyclopentadienyl-substituted methane derivatives ("pentamethylcyclopentadienyl-carbon compounds") reactions of (pentamethylcyclopentadienyl)lithium with halomethans, formates, and corbon dioxide were investigated.While treatment with tri- and tetrahalomethanes leads to benzene derivatives via molecular rearrangement, reactions with formates and carbon dioxide yield pentamethylcyclopentadienyl-substituted methane derivatives.Attempts to prepare disubstituted species show the formation of by-products only.

- SYNTHESIS, STRUCTURES, AND REACTIVITIES OF SOME PENTAMETHYLCYCLOPENTADIENYL-SULPHUR COMPOUNDS

The pentamethylcyclopentadienyl-sulphur compounds S(C5Me5)2 (1) and S2(C5Me5)2 (2) have been prepared by the reaction of Li(C5Me5) with SCl2 and S2Cl2, respectively.Compounds (1) and (2) were characterised by n.m.r. and mass spectroscopy.The X-ray crystal structure of (1) has been determined.Compound (1) crystallises in the monoclinic space group P21/c (no. 14), with a = 10.375(2), b = 11.274(2), c = 16.132(9) Angstroem, β = 91.92(3) deg, and Z = 4.The reaction of (1) with results in the known cluster compound, (3), the identy of which was confirmed by X-ray crystallography.Unsuccessful attempts were made to prepare cations of the type n+ by (i) oxidation of (1) and (2), or (ii) the reaction of S(C5Me5)Cl (Prepared in situ) with Al2Cl6.Cyclic voltammetric experiments on (1) and C5Me5H suggest that oxidation occurs at the carbocyclic ring rather than at the sulphur atom.
