This invention relates to a carbene complex of metal salt represented by the formula:
[T−M(R)c]n
wherein, R is a monoanionic group; c is 1 or 2; M is a Li or Mg; T is a cyclic carbene ligand; and n is selected from the group of integers comprising 1 to 24 wherein the complex has 50% or less decomposition when stored in 0.01 molar benzene at 23° C. for a period of 1 hour. This invention also relates to transition-metal-carbene complexes prepared from such carbene complexes of metal salts, where the transition-metal-carbene complex is represented by the formula: [M*(T)(L0)q(L1−)s(L2−)t]g, where M* is a transition metal from Group 6, 7, 8, 9, 10, 11 or 12, T is a cyclic carbene ligand, L0 is a neutral ligand, L1− is a monoanionic ligand, L2− is a dianionic ligand, q is 0, 1, 2, 3 or 4, s is 0, 1, 2, 3, or 4, t is 0, 1, 2, 3, or 4, g is the overall charge of the molecule. The transition-metal-carbene complexes may be used for synthesis reactions, including metathesis of olefins.
