“…These observations suggested the intriguing possibility of a metal–deuterium exchange reaction occurring between 1 and the NMR solvent. Logically, this would result in the generation of aryl anions (C 6 D 5 – ), whose π-type interaction with Li + could then account for the observed high-field 7 Li NMR resonances (as previously reported in aryl(amido)cuprates) 3941…”

“…For example, adducts such as 28 have introduced new possibilities regarding the elimination of LiX from Lipshutz-type cuprates. Of course, these data have implications for our view of the solution behaviour of lithium cuprates and direct monitoring of the aggregation behaviour of these systems in solution, examples of which have been reported recently, 42 will represent an increasingly significant part of forthcoming work. Attention is also turning to heteroleptic cuprates.…”

“…40 Moving to the similarly underpopulated field of heteroleptic organyl(amido)cuprate structural chemistry, 41 19 fails to demonstrate the aggregation behaviour of aryl(amido)cuprate MesCu(NBz 2 )Li 23 (Bz = benzyl; Fig. 11), 42 the head-totail dimeric structure of which confirmed theoretical expectations. Even in solution, the dimer showed negligible signs of deaggregation.…”

“…While Gilman-type homoleptic bis(organyl)- 9,10 and heteroleptic organyl(amido)cuprates 11 have been experimentally studied, 95 theory has suggested a preference for head-to-tail dimerization in the heterocuprate case. 31 This has been experimentally confirmed in the dimer of MesCu[N(CH 2 Ph) 2 ]Li, 13 though the presence of Lewis base has been shown to result in monomer formation. 12,14 In 100 contrast to the study of homo-and heteroleptic cuprates bearing organyl and/or amido ligands, that of phosphidocuprate chemistry is at a significantly less advanced stage, with the structure of (Bu t 2 P) 2 CuLi•2thf representing the only reported structure analogous to 3.…”
