Synthesis and characterization of alkynyl complexes of groups 1 and 2.
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-iPr(2)C(6)H(3)N)(2)) with PhC[triple bond]CH in THF yields the dimeric alkynyl complex [nacnacSr(thf)(mu-C[triple bond]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.
