A zirconium amine bis(phenolate) catalyst that is capable of simultaneously producing both oligomers and polymers of 1-hexene was investigated. It was found that the polymer produced has more branching than the commonly encountered poly(1-hexene), su

Five new structural analogues of a previously studied group IV amine bis(phenolate) catalyst, Zr(ONNEt2O)Bn2, have been synthesized and tested for oligomerization activity. These structural variations encompass longer alkyl groups, propyl and butyl,

1-Hexene polymerization using four zirconium-based amine bis(phenolate) catalysts, Zr[2-R-4-tBu-ONNO]Bn2 (where R = methyl (1), ethyl (2), isopropyl (3), and tert-butyl (4)), was examined to establish the effect of ligand sterics on kinetics and ster

A series of 1,2-diacyl cyclopentadienyl tricarbonyl manganese and rhenium complexes, [M(CO)3{η5-1,2-C5H3(CO-(R)2}] (3a–c and 4a–b), were isolated utilizing a straightforward, 3-step route. The synthetic pathway began with a 1,2-diacyl cyclopenta

Pyridazines are an important class of heterocyclic compounds as a result of their materials and commercial applications. The synthesis of 5,6-fused ring pyridazines 2a–h from 1,2-diacylcyclopentadienes (fulvenes) 1a–h is described herein. This ro
