Abstract The synthesis of N ‐heterocyclic carbene adducts of alkynyl lithium and magnesium is achieved, and different degrees of association are observed. Reaction of strontium amide nacnacSrN(SiMe 3 ) 2 (thf) (nacnac=CH(CMe2,6‐ i Pr 2 C 6 H 3 N) 2 ) with PhC≡CH in THF yields the dimeric alkynyl complex [nacnacSr(thf)(μ‐C≡CPh)] 2 which shows an interesting coordination geometry around the metal center. The compound retains the THF molecules, unlike its lighter congener, even in hydrocarbon solvents.
