    • 2 species by treatment with MAO that failed. The only exception is 4c, which showed some activity after reaction with MAO presumably due to the presence of four intramolecular ether fragments per palladium atom. A detailed investigation on this effect and on the polymerization properties of 4c is right now underway.

    • note
    • We had problems controlling the reaction temperature due to these unexpected high activities and switched therefore to a 2 L reactor setup, equipped with an internal cooling device. However, the activity values given in Table 4 can only be first estimates due to the rapid precipitation of the high molecular polymers. We suggest that the real values are substantially higher (cf. section on hydrogen addition).
