WebNorbornene or norbornylene or norcamphene is a highly strained bridged cyclic hydrocarbon. It is a white solid with a pungent sour odor. The molecule consists of a cyclohexene ring with a methylene bridge between carbons 1 and 4. The molecule carries a double bond which induces significant ring strain and significant reactivity. WebWe report here a new type of polynorbornene structure that includes in the polymer backbone both 2, 3-bicyclic and cyclohexenylmethyl fragments via vinylic addition polymerization and a ring opening of norbornene (NB) by β-C elimination, and therefore can be labeled as VA/RO-PNB.Results and discussion Complexes [Ni(R F) 2 L 2] (R F = C 6 F 5, …
