TL;DR: The synthesis and characterisation of a number of group nine complexes containing the recently reported ligand, diphenyl-2-(3-methyl)indolylphosphine, were investigated for their activity in the catalytic transfer hydrogenation of ketones and found to be moderately active catalysts.
Abstract: The synthesis and characterisation of a number of group nine complexes containing the recently reported ligand, diphenyl-2-(3-methyl)indolylphosphine, is presented herein. The complexes [RhCl(COD){PPh2(C9H8N)}] (1), [IrCl(COD){PPh2(C9H8N)}] (2), [RhCl(NBD){PPh2(C9H8N)}] (3) and [Rh(COD)(MeCN){PPh2(C9H8N)}]BF4 (4) (where COD = 1,5-cyclooctadiene, NBD = 2,5- norbornadiene) have been structurally characterised by X-ray crystallography. The complex [Rh2(COD)2{N(Me)C(H)Ph)}{PPh2(C9H8N)}][BF4]2 (8) was also isolated and structurally characterised. Complex 8 contains a ‘[Rh(COD)]’ fragment coordinated to the aromatic ring of the indolyl group, providing the first example of a η6 coordination mode for this ligand. The synthesised complexes were investigated for their activity in the catalytic transfer hydrogenation of ketones and found to be moderately active catalysts.

TL;DR: In this paper, a novel synthesis of episulfoxides having the norbornane skeleton is possible by use of a rhodium catalyst to effect SO transfer from trans-stilbene episulfoxide to norbornene or norbornadiene.
Abstract: A novel synthesis of episulfoxides having the norbornane skeleton is possible by use of a rhodium catalyst to effect SO transfer from trans-stilbene episulfoxide to norbornene or norbornadiene. Analogous Rh2(OAc)4 catalysed sulfur transfer to these alkenes is also possible using propylene sulfide as the sulfur source. These methods did not give useful yields of products with alternative types of alkene substrate.
A novel type of chiral lithium amide base reaction, involving the rearrangement of certain types of symmetrical ring-fused episulfoxides, gives alkenyl sulfoxide products in up to 88% ee. The structures of the products, including absolute stereochemistry, were assigned based on X-ray crystal structure determinations.

TL;DR: Oligonuclear ferrocene derivatives containing either sulfur or disulfur bridges were obtained by three methods as mentioned in this paper : 1) The reaction of 1,1′-dilithioferrocene, fcLi 2, with diferrocenyldisulfane, Fc-SS-Fc (1a), FcS-fc-ss-SSFc(S 3 ), fcS 3 ) and FcSH 2 with norbornadiene (1:1) gave yellow products the majority of which are insoluble in organic

TL;DR: Nickel atoms react with buta-1,3-diene to produce dodeca-2,6,10-triene-1 12-diylnickel; nickel atoms also trimerise acetylenes, dimerise norbornadiene, and isomerise olefins, probably via a π-allyl hydride mechanism as discussed by the authors.
