“…[29, 191b] The reaction of triphenylmethylbromide and Me 2 CuLi generated an ESRactive triphenylmethyl radical; this may, however, be regarded as a special case. [198] Intramolecular cyclization of an olefinic iodide in the presence of an organocopper reagent has been taken as possible but not conclusive evidence of SET. [199] …”

“…The reaction between triphenylmethyl bromide and Me 2 CuLi generated an ESR-active triphenylmethyl radical, although this may be regarded as a special case [119]. On the basis of trapping experiments using styrene, it was concluded that dialkylcuprate substitution reactions of primary and secondary alkyl iodides may proceed by an SET mechanism, whereas those of primary and secondary bromides do not [120].…”

“…[146] Aus diesem entsteht dann durch reduktive Eliminierung das Kreuzkupplungsprodukt. [198] Die intramolekulare Cyclisierung eines Olefiniodids in Gegenwart eines Organokupferreagens wurde als möglicher, aber nicht schlüssiger Beweis für einen SET angesehen. Die vorgeschlagene Beteiligung eines Cu III -Zwischenprodukts basiert auf einer Analogie zur Chemie von Lithiumdiorganoauraten(i) R 2 Au I Li.…”
