27. n = 1.14); this result also indicates that the living polymerization is efficient. A slightly lower efficiency of the initiation than the ideal living polymerization is ascribed to slow or insufficient activation of the Co complex by MMAO. See also: P. Mehrkhodavandi, R. R. Schrock, L. L. Pryor, Organometallics 2003, 22, 4569-4583.
28. Polymerization of methylenecyclopropane catalyzed by Zr and Ni complexes is proposed to involve the 1,2-insertion of the monomer into the M-C σ bond (See refs [6b] and [7]). The 1,2-insertion of monomer is also supported by an end functionalization experiment.
29. III complex is most likely the active species in the reaction.
