TL;DR: Phenylacetylene reacts with norbornadiene at 100 °C in THF to give 3-phenylethinylnortricyclene in 45 % chemical yield and 60 % optical yield as mentioned in this paper.
Abstract: Phenylacetylene reacts with norbornadiene at 100 °C in THF to give 3-phenylethinylnortricyclene in 45 % chemical yield and 60 % optical yield, [Rh(nbd)(−)-Norphos]PF 6 (1 mol%) being used as a catalyst. Replacement of (−)-Norphos by other diphosphanes leads to other products or product mixtures.

TL;DR: Rhodium complexes with planar chiral phosphinoferrocenyl thioether ligands [Rh(P,SR)(diene)X] (R = Me, But, Ph, Bn, diene is cyclooctadiene (COD), X = Cl, BF4) catalyze hydrogenation of ketones, imines, and heteroaromatic compounds; in the case of acetophenone, the enantioselectivity reached 60% ee.
Abstract: Rhodium complexes with the planar chiral phosphinoferrocenyl thioether ligands [Rh(P,SR)(diene)X] (R = Me, But, Ph, Bn, diene is cyclooctadiene (COD) or norbornadiene (NBD), X = Cl, BF4) catalyze hydrogenation of ketones, imines, and heteroaromatic compounds; in the case of acetophenone, the enantioselectivity reached 60% ee. Similar iridium complexes demonstrate a good activity in the hydrogenation of imines, the maximal enantioselectivity in the case of N-phenyl-N-(1-phenylethylidene)amine was about 40% ee.

TL;DR: In this article, it has been demonstrated that polymer-analogous reactions are an attractive alternative to prepare polymers with pendent ferrocene units in the main chain, which can be obtained from interfacial condensation reaction between Ferrocene-1, 1, 1′-dicarbonic acid dichloride with α, ω-diamines.
Abstract: Polymers with pendent ferrocene units are synthesized by radical and anionic methods. It has been demonstrated that polymer-analogous reactions are an attractive alternative to prepare those polymers. Polymers with ferrocene units in the main chain are available from interfacial condensation reaction between ferrocene-1,1′-dicarbonic acid dichloride with α, ω-diamines. Addition of ferrocene-1,1′-dithiol onto norbornadiene yields a polymer with repeating units from ferrocene disulfide and norbornene and nortricyclane end-groups. End-capping reactions of α, ω-dimercapto-telechelics with vinylferrocene yield polymers with ferrocene end-groups.

TL;DR: In this article, an organoruthenium compound for use in chemical vapor deposition which does not require the coexistence of oxygen during the thin film formation, and moreover, is liquid at ordinary temperature, thereby having good handleability and recyclability.
Abstract: The present invention is an organoruthenium compound for use in production of a ruthenium or ruthenium compound thin film by chemical vapor deposition, including ruthenium and an arene group and norbornadiene both coordinated to the ruthenium and represented by the following formula. The present invention is an organoruthenium compound for use in chemical vapor deposition which does not require the coexistence of oxygen during the thin film formation, and moreover, is liquid at ordinary temperature, thereby having good handleability and recyclability. wherein the substituents, R 1 to R 6 , of the arene group are each hydrogen or an alkyl group, and the total number of carbons of R 1 to R 6 (R 1 +R 2 +R 3 +R 4 +R 5 +R 6 ) is 6 or less.
