TL;DR: In this paper, the preparation of a polymer-supported ruthenium alkylidene metathesis catalyst is described, which is used to initiate a ring-opening metathesizing polymerization of norbornene derivatives onto a polymer support to prepare novel highloading resins for use in combinatorial chemistry.

TL;DR: The potential energy surfaces for the thermal reactions of bicyclo[3.2.0] and norbornene have been explored with density functional theory at the Becke3LYP/6-31G* level.
Abstract: The potential energy surfaces for the thermal reactions of bicyclo[3.2.0]hept-2-ene and norbornene have been explored with density functional theory at the Becke3LYP/6-31G* level. Both concerted and diradical pathways for the retro-Diels−Alder reaction of norbornene have been examined, and the activation parameters and 13C primary kinetic isotope effects predicted for the concerted pathway are in excellent agreement with experimental data. The concerted mechanism is favored over the lowest energy stepwise diradical route by 12.4 kcal/mol. For the orbital symmetry-allowed suprafacial-inversion (si) pathway of the [1,3] sigmatropic rearrangement of bicyclo[3.2.0]hept-2-ene to form norbornene, a mechanism involving a transition state which leads to a broad diradical plateau on the potential energy surface is predicted. Implications of these surfaces, which differ substantially from those obtained by semiempirical calculations, are also discussed.

TL;DR: Carbometallation of α-olefins, as well as of those containing functional groups, and of norbornene derivatives has been investigated with alkyl-magnesium and -aluminium compounds and found to proceed under mild conditions in the presence of catalytic quantities of Zr and Ti complexes.

TL;DR: In this paper, the M06 density functional was used to predict the stability of conformers for the ring-closing metathesis of norbornene in Grubbs catalysis.
