The zwitterionic allyl complex 1 (R n = 1,3‐(SiMe 3 ) 2 ) is a new catalyst type for the polymerization of ethene under mild conditions. The propensity of these and similar zwitterionic complexes for CH activation and rearrangements is very sensitive to steric conditions. The reactions provide evidence for a new, surprisingly facile catalyst‐deactivation mechanism.
