Synthesis and characterization of Ir(III) metallacycles derived from thiophene and related compounds: models for the hydrodesulfurization process
… and 5-methyl thiazole yields the C-S addition metallacycles (Me₃P)₃Ir-(CH=CHCH=S)CI (I), \ (Me3P)3Ir-(CH=NCH=CHS)CI (II), (Me3P)3Ir-CCH=NC(CH3)=CHS)CI (III) and (Me3P)3Ir (CH=NCH=C(CH3)S)CI (IV), respectively. These compounds were characterized using the following methods: ¹H NMR, ¹³C NMR, ³¹P …

Synthesis And Characterization Of Group 5 Metal Complexes Containing Pyrazolate, Amidate, And Related Ligands As Potential Precursors For Thin Film Growth By Atomic Layer Deposition
… and Ta(IV) metal centers and afford six membered metallacycles that are analogous to metallapyrimidines and metallapyrimidiniums. Two other pyrazolate ligands are found to be intact and the final oxidation state of the complexes were +5. Those metallacycles are nearly planer, conjugated, have 6 …

An EPR and DFT investigation of the products formed in the reaction of group 11 metal atoms with three-membered heterocyclic compounds
… Cu atoms and oxiranes or thiirane yield novel metallacycles, i.e., cupraoxetane and cuprathietane, respectively. DFT calculations were also used to support the structural assignments of the M-XCH2CH2 complexes.

Synthesis and Characterization of Transition Metal Complexes of Multitopic, Third-Generation, Phenylene-Linked Bis(1-Pyrazolyl)Methane Ligands
… environment forming unusually sized mononuclear metallacycles. The silver(I) complexes of the tetratopic and hexatopic ligands form double, mononuclear metallacycles, a new structural form. In the silver complexes of the tetratopic ligand, the double, mononuclear metallacycles are formed by two …

Synthesis and reactivities of titanocene-oxo complexes and rhodium-catalyzed oxidative amidation
… to generate isolable four- or six-membered metallacycles. The reversed reaction, retro-cycloaddition, occurred at room temperature and could achieve high conversion depending on the stereoelectronic properties of the titanacycles. This facile cycloreversion is significantly different from …
