“…As mentioned before (see Group 10), a bimetallic species showing a Pt–Cu interaction supported by a bridging CH 3 group has been described by Chen et al . Two further complexes of this class, which have been provided recently by Bertz and Ogle, consist in cuprate anions supported by an alkene ligand in one case (vide infra, Reactivity Section), and by a phenyltiolate in the other one (Scheme ) . A rare example of a photoluminescent copper cluster with bridging methyl groups was reported in 2010 by Cavell and co‐workers …”

Organometallic chemistry can be considered as a wide area of knowledge that combines concepts of classic organic chemistry, i.e. based essentially on carbon, with molecular inorganic chemistry, especially with coordination compounds. Transition metal methyl complexes probably represent the simplest and most fundamental way to view how these two major areas of chemistry combine and merge into novel species with intriguing features in terms of reactivity, structure, and bonding. Citing more than 500 bibliographic references, this review aims to offer a concise view of recent advances in the field of transition metal complexes containing M-CH3 fragments. Taking into account the impressive amount of data that are continuously provided by organometallic chemists in this area, this review is mainly focused on results of the last 5 years. After a panoramic overview on M-CH3 compounds of groups 3 to 11 which includes the most recent landmark findings in this area, two further sections are dedicated to methyl-bridged complexes and reactivity.

“…The former lithium–oxygen bond length is significantly less than the latter bond lengths (see Figure 1 caption). Lithium methyl(di‐ tert ‐butylphosphido)cuprate(I)15 and lithium methyl(phenylthio)cuprate(I)16 also have structures in which a lone pair of electrons is donated from a heteroatom to a (THF) 3 Li + moiety in the solid state; they can be considered contact ion pairs 2…”

“…This technique has recently been advanced for the characterisation of other organometallic aggregates. [53][54][55][56][57][58] The most commonly reported method involves obtaining empirical formula weights (FW) of unknown aggregates from their experimentally determined diffusion coefficients (D)a nd then comparing with FW of predicted species. However,a lthough this method works well for organometallic speciesi nvolving lighter metals (such as lithium [55] )w hich tend to possess consistent densities (ca.…”

A series of copper(I) alkylamide complexes have been synthesised; copper(I) dicyclohexylamide (1), copper(I) 2,2,6,6-tetramethylpiperidide (2), copper(I) pyrrolidide (3), copper(I) piperidide (4), and copper(I) benzylamide (5). Their solid-state structures and structures in [D6]benzene solution are characterised, with the aggregation state in solution determined by a combination of DOSY NMR spectroscopy and DFT calculations. Complexes 1, 2 and 4 are shown to exist as tetramers in the solid state by X-ray crystallography. In [D6]benzene solution, complexes 1, 2 and 5 were found by using 1H DOSY NMR to exist in rapid equilibrium between aggregates with average aggregation numbers of 2.5, 2.4 and 3.3, respectively, at 0.05 m concentration. Conversely, distinct trimeric, tetrameric and pentameric forms of 3 and 4 were distinguishable by one-dimensional 1H and 1H DOSY NMR spectroscopy. Complexes 3–5 are found to react stoichiometrically with iodobenzene, in the presence or absence of 1,10-phenanthroline as an ancillary ligand, to give arylamine products indicative of their role as potential intermediates in the modified Ullmann reaction. The role of phenanthroline has also been explored both in the stoichiometric reaction and in the catalytic Ullmann protocol.
