title: Experimental evidence for large ring metallacycle intermediates in polyethylene chain growth using homogeneous chromium catalysts.
abstract: Deuterio-ethylene labeling studies on two homogeneous chromium ethylene oligomerization catalysts show that chain propagation proceeds via metallacyclic intermediates; reactions performed in the presence of 1-nonene show no incorporation of the higher olefin, strongly implicating the involvement of large ring metallacycles.
