“…Lorsque cette reaction n'est pas possible, en raison de l'absence de cet hydrogkne ou de la geometrie defavorable, la decomposition par rupture homolytique d'une liaison titane-carbone intervient [2]. La decomposition thermique du tktracyclohexyltitane suit une evolution difftrente selon la presence ou l'absence du solvant [3]. Le rble de destabilisation par le chlorure de magnesium, forme lors de la synthise de composes tetraalkylks du titane a partir d'un reactif de Grignard et du tetrachlorure de titane, a de plus ett: dCmontr6 [4].…”

The formation of the high-valent iron complex [Fe(cyclohexyl) 4 ]f rom Fe II under reducing conditions is best explained by disproportionation of at ransient organoiron intermediate which is driven by dispersive forces between the cyclohexyl ligands and the formation of short and strong Fe À C bonds.The (meta)stability of this diamagnetic complex (S = 0) is striking if one considers that it has empty d-orbitals at its disposal and contains,atthe same time,noless than twenty Hatoms available for either a-orb-hydride elimination.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: http://dx.

The fluorinated alcohols, (CF3)3COH (RF9OH) and (CF3)2MeCOH (RF6OH), react with W(NR)2Cy2 (Cy = Cyclohexyl; R = 2,6‐diisopropylphenyl or 1‐adamantyl) in C6D6 at 55°C to give cyclohexylidene complexes. Traditional routes to terminal alkylidene complexes (neopentylidene or neophylidene) have used either triflic acid or HCl (rarely), but relatively weak fluorinated acids are sufficient and active bisalkoxide catalysts are therefore prepared directly. An ahydrogen abstraction reaction to give a cyclohexylidene complex from a biscyclohexyl appears to be as facile as ahydrogen abstraction to give a neopentylidene or neophylidene ligand, but isomerization of a cyclohexene formed through b hydrogen abstraction is also a possibility. The ORF9 ligands can be replaced readily with dimethylpyrrolide (Me2Pyr) or other more basic alkoxides. Single crystal X‐ray studies were carried out on W(NAr)2Cy2, W(NAr)(ORF9)2(C6H10)(ArNH2), W(NAr)(ORF6)2(C6H10)(ArNH2), W(NAd)(ORF9)2(C6H10)(AdNH2), W(NAr)(O‐i‐PrF6)3Cy, and W(NAd)(h1‐Me2Pyr)2(C6H10) (C6H10 = cyclohexylidene).
