[(MesNCH(2)CH(2))(2)NMe]ZrMe}[B(C6F5)(4)] and intermediates in the polymerization reaction of 1-hexene that are formed from it decompose as a consequence of CH activation in an ortho methyl group in the mesityl substituent. The intermediates in the polymerization reaction decompose significantly more readily than does [(MesrNCH(2)CH(2))(2)NMe]ZrMe }[B(C6F5)(4)] On the other hand, analogous cationic complexes that contain the [(2,6-Cl2C6H3NCH2 CH2)(2)NMe](2-) ligand a re re la ti very stable and will consume 1-hexene in a strictly first-order and apparently living manner at 0 degreesC in chlorobenzene.
