Abstract
The understanding and control of stereoselectivity is a central aspect in ring-opening metathesis polymerization (ROMP). Herein, we report detailed quantum chemical studies on the reaction mechanism of E-selective ROMP of norborn-2-ene (NBE) with Mo(N-2,6-Me2-C6H3)(CHCMe3)(IMes)(OTf)2 (1, IMes = 1,3-dimesitylimidazol-2-ylidene) as a first step to stereoselective polymerization. Four different reaction pathways based on an ene syn or ene anti approach of NBE to either the syn- or anti-isomer of the neutral precatalyst have been studied. In contrast to the recently established associative mechanism with a terminal alkene, where a neutral olefin adduct is formed, NBE reacts directly with the catalyst via [2 + 2] cycloaddition to form molybdacyclobutane with a reaction barrier about 30 kJ mol-1 lower in free energy than via the formation of a catalyst-monomer adduct. However, the direct cycloaddition of NBE was only found for one out of four stereoisomers. Our findings strongly suggest that this stereoselective approach is responsible for E-selectivity and point toward a substrate-specific reaction mechanism in olefin metathesis with neutral Mo imido alkylidene N-heterocyclic carbene bistriflate complexes.

Abstract
Despite their excellent selectivities and activities, Mo‐and W‐based catalysts for olefin metathesis have not gained the same widespread use as Ru‐based systems, mainly due to their inherent air sensitivity. Herein, we describe the synthesis of air‐stable cationic‐at‐metal molybdenum and tungsten imido alkylidene NHC nitrile complexes. They catalyze olefin metathesis reactions of substrates containing functional groups such as (thio‐) esters, (thio‐) ethers and alcohols without the need for prior activation, for example, by a Lewis acid. The presence of a nitrile ligand was found to be essential for their stability towards air, while no decrease in activity and productivity could be observed upon coordination of a nitrile. Variations of the imido and anionic ligand revealed that alkoxide complexes with electron‐withdrawing imido ligands offer the highest reactivities and excellent stability compared to analogous triflate and halide complexes.

Abstract
![]()
A series of neutral
molybdenum imido alkylidene N-heterocyclic carbene
(NHC) bistriflate and monotriflate monoalkoxide
complexes as well as cationic molybdenum imido alkylidene triflate
complexes have been subjected to NMR spectroscopic, X-ray crystallographic,
and reaction kinetic measurements in order to gain a comprehensive
understanding about the underlying mechanism in olefin metathesis
of this new type of catalysts. On the basis of experimental evidence
and on DFT calculations (BP86/def2-TZVP/D3/cosmo) for the entire mechanism,
olefinic substrates coordinate trans to the NHC of neutral 16-electron
complexes via an associative mechanism, followed by dissociation of
an anionic ligand (e.g., triflate) and formation of an intermediary
molybdacyclobutane trans to the NHC. Formation of a cationic complex
is crucial in order to become olefin metathesis active. Variations
in the NHC, the imido, the alkoxide, and the noncoordinating anion
revealed their influence on reactivity. The reaction of neutral 16-electron
complexes with 2-methoxystyrene is faster for catalysts bearing one
triflate and one fluorinated alkoxide than for catalysts bearing two
triflate ligands. This is also reflected by the Gibbs free energy
values for the transition states, ΔG‡303, which are significantly lower for catalysts bearing
only one triflate than for the corresponding bistriflate complexes.
Reaction of a solvent-stabilized cationic molybdenum imido alkylidene N-heterocyclic carbene (NHC) monotriflate complex with 2-methoxystyrene
proceeded via an associative mechanism too. Reaction rates of both
solvent-free and solvent-stabilized cationic Mo imido alkylidene NHC
catalysts with 2-methoxystyrene are controlled by the cross-metathesis
step but not by adduct formation.

Abstract
The methods for synthesis of promising norbornene monomers from norbornadiene and quadricyclane are summarized. A strategy for their synthesis is discussed, combining theoretical and experimental approaches to the selection of catalysts and the conditions for carrying out stereoselective reactions. The mechanisms of catalytic reactions of synthesis of norbornene monomers, as well as the progress in the macromolecular design of functional polymeric materials based on them, are considered. The data on industrial processes of production of polynorbornenes and areas of their use are presented.
The bibliography includes 297 references.

Abstract
The concepts of functional precision polymers and the latest accomplishments in their synthesis are summarized. Synthetic concepts based on chain growth polymerization are compared to iterative synthetic approaches. Here, the term "functional precision polymers" refers to polymers that are not solely hydrocarbon-based but contain functional groups and are characterized by a highly ordered primary structure. If insertion polymerization is used for their synthesis, olefin metathesis-based polymerization techniques, that is, ring-opening metathesis polymerization (ROMP), acyclic diene metathesis (ADMET) polymerization, and the regio- and stereoselective cyclopolymerization of α,ω-diynes are almost exclusively applied. Particularly with regio- and stereospecific ROMP and with cyclopolymerization, the synthesis of tactic polymers and copolymers with high regio-, stereo-, and sequence control can be accomplished; however, it requires carefully tailored transition metal catalysts. The fundamental synthetic concepts and strategies are outlined.
