TL;DR: A C2-symmetric norbornadiene derivative was prepared and used for the rhodium-catalyzed asymmetric addition of organoboron and -tin reagents to alpha,beta-unsaturated ketones, which gave high yields of the 1,4-addition products with up to 99% enantioselectivity.
Abstract: As a new type of chiral ligand, a C2-symmetric norbornadiene derivative (1R,4R)-2,5-dibenzylbicyclo[2.2.1]hepta-2,5-diene (1) was prepared and used for the rhodium-catalyzed asymmetric addition of organoboron and -tin reagents to α,β-unsaturated ketones, which gave high yields of the 1,4-addition products with up to 99% enantioselectivity.

Abstract: : Benzonorbornadiene 2,3-dicarbomethoxynorbornadiene and 2,3- bis(trifluoromethyl)norbornadiene can be polymerized by Mo(CH-t-Bu)(NAr)(O-t-Bu) 2(Mo(CH-t-Bu)) in a well-behaved living manner to give essentially monodisperse homopolymers. Two of the polymers and (especially) poly 5 are highly trans, and are believed to be tactic. The rate of polymerization is approximately thirty times faster at room temperature, a factor of approximately ten of which can be ascribed to the lower reactivity and the remainder to the lower reactivity relative to 7-Isopropylidene-2-3-dicarbomethoxynorbornadiene is not polymerized at all by Mo(CH-t-Bu), although it does react with Mo(CH-t-Bu). An X-ray structure shows it to be a pseudo-tetrhedral species containing a syn alkylidene ligand (substituent pointing toward the imido nitrogen atom).

TL;DR: The racemic and meso diastereomers of an electron-rich binucleating tetraphosphine ligand have been used to prepare homobimetallic rhodium norbornadiene complexes, giving both a high rate of reaction and high regioselectivity for linear aldehydes.
Abstract: The racemic and meso diastereomers of an electron-rich binucleating tetraphosphine ligand have been used to prepare homobimetallic rhodium norbornadiene complexes. The racemic bimetallic Rh complex is an excellent hydroformylation catalyst for 1-alkenes, giving both a high rate of reaction and high regioselectivity for linear aldehydes, whereas the meso complex is considerably slower and less selective. A mechanism involving bimetallic cooperativity between the two rhodium centers in the form of an intramolecular hydride transfer is proposed. Mono- and bimetallic model complexes in which the possibility for bimetallic cooperativity has been reduced or eliminated are very poor catalysts.

TL;DR: Ruthenium-catalyzed oxidative C-H bond olefination of N-methoxybenzamides using an oxidizing directing group with a broad substrate scope is reported.
Abstract: Ruthenium-catalyzed oxidative C–H bond olefination of N-methoxybenzamides using an oxidizing directing group with a broad substrate scope is reported. The reactions of N-methoxybenzamides with acrylates in MeOH and styrene (or norbornadiene) in CF3CH2OH afforded two types of products.
