16 Aug 1976TL;DR: In this paper, a process of producing a ring-opening polymerization product of a norbornene derivative containing at least one polar group or aromatic group using a catalyst system prepared from an organometallic compound was described.
Abstract: A process of producing a ring-opening polymerization product of a norbornene derivative containing at least one polar group or aromatic group, a norbornadiene derivative containing at least one of said groups or a cycloolefin using a catalyst system prepared from an organometallic compound and the reaction product of tungsten oxide or molybdenum oxide and a phosphorus pentahalide or phosphorus oxytrihalide or these compounds and other third components. The catalyst system possesses a high polymerization activity.

TL;DR: In this article, the authors show that cyclization of cyclopentane derivatives is induced by zinc and acid or by BuSnH4, depending on the relative intensity of the 19 F NMR spectrum with relative intensities of 3:2.

TL;DR: In this paper, the authors report on the bond coupled electron transfer (BCET) isomerization reaction of norbornadiene (NB) to quadricyclane (Q).
Abstract: In this paper, we report on the bond coupled electron transfer (BCET) isomerization reaction of norbornadiene (NB) to quadricyclane (Q). We have used several triplet sensitizers to examine electron...

TL;DR: In this article, the bis(pentaammineruthenium(II)) complex of dicyanonorbornadiene has been prepared and characterized, and it exhibits an intervalence transition in the 1000−1600 nm range.
Abstract: The bis(pentaammineruthenium(II)) complex of dicyanonorbornadiene has been prepared and characterized. Its photochemical conversion into a dicyanoquadricyclane complex by irradiation in methanol has been followed by UV−visible spectroscopy, IR spectroscopy, 1H NMR spectroscopy, and cyclic voltammetry. The dicyanonorbornadiene complex exhibits an intervalence transition in the 1000−1600 nm range when oxidized to the ruthenium(II)−ruthenium(III) state. This allows the determination of the effective coupling Vab through the dicyanonorbornadiene ligand, which is found as 0.023 eV. No such band is observed in the case of the dicyanoquadricyclane complex. These results show the possibility to modulate an intramolecular electron transfer process by using a photoisomerizable bridging ligand.
