TL;DR: In this paper, a three-dimensional X-ray crystal structure analysis has shown that the product obtained by replacement of norbornadiene in tetracarbonylnorbornadienemolybdenum by 2-allylphenyldiphenylphosphine is the compound tetracaronyl[diphenymyl-2-(prop-cis-1-enyl)phenyl phosphine]molybDENum(0), the ligand having rearranged.
Abstract: A three-dimensional X-ray crystal structure analysis has shown that the product obtained by replacement of norbornadiene in tetracarbonylnorbornadienemolybdenum by 2-allylphenyldiphenylphosphine is the compound tetracarbonyl[diphenyl-2-(prop-cis-1-enyl)phenylphosphine]molybdenum(0), the ligand having re-arranged.Photographic measurements were made at 155°K. In a triclinic cell having a= 10·53, b= 13·26, c= 9·36 A(10–10 m), α= 100·2, β= 91·0, γ= 118·2°, and space group P, there are two molecules. The structure was solved from Patterson and electron-density difference syntheses and refined by least squares to R 0·09. The molybdenum atom is octahedrally co-ordinated by one phosphorus atom, Mo–P, 1·517 ± 0·005 A, four carbonyl groups, Mo–C, 1·96–2·05, and by the olefin group, Mo–C, 2·45 and 2·52 ± 0·02 A. Both carbon atoms of the olefin lie approximately in the plane containing their mid-point, and the molybdenum and phosphorus atoms; the C–C bond length is 1·39 ± 0·03 A. The three P–C bonds average 1·84 ± 0·02 A, the eighteen C–C bonds in the phenyl rings average 1·40 ± 0·03 A, the four CO bonds average 1·14 ± 0·03 A, the C–C bond from the olefin group to the terminal methyl group is 1·44 ± 0·03 A and that to the phenyl ring is 1·51 ± 0·03 A.

TL;DR: The anionic triosmium cluster [N(PPh3)2] reacts with [Rh(nbd)Cl)2 (nbd = norbornadiene) in the presence of AgPF6 to give two new high-nuclearity osmium-rhodium clusters [Os12Rh9(CO)44(µ3-Cl)] 1 and [Os4Rh3 (µ 3-H)(CO)14(´3-CO)(η4-C7H8)2], 2 in moderate yields as discussed by the authors

TL;DR: In this article, a ring opening polymer with high yields was obtained by ring-opening polymerization of norbornadiene derivatives, using a catalyst system obtained from a reaction product of an organometallic compound, an oxide of W and/or Mo and a Lewis acid and a reactive group-containing polymer.
