Cross Metathesis

The scope of ruthenium (Ru)-catalyzed cross metathesis (CM) of allyl-decorated polyhedral oligomeric silsesquioxanes (POSS) was explored. A variety of different commercial and non-commercial ruthenium complexes were tested to determine that the nitro-activated Ru catalyst is optimal for this transformation. The reported transformation was used to prepare selected hybrid steroid-POSS compounds.

Partial Degradation

Polybutadiene (I) containing 91% of 1,4-(cis-trans) units and 9% of 1,2-units in the presence of vinyltriethoxysilane (II) and ruthenium catalysts RuCl2(PPh3)3 (III), RuHCl(CO)(PPh3)3 (IV), and [RuCl2(CO)3]2 (V) at 100-130°C undergoes functionalization and (or) partial degradation as an effect of competitive silylative coupling of =C-H and cross-metathesis of I with II. Significant degradation of I occurs at lower temperatures (100-110°C) (particularly when the process is carried out in air), but exclusive functionalization of I is observed at higher temperature (120-130°C) regardless of the atmosphere (air or argon) used.Key words: functionalization, degradation, polybutadiene, ruthenium complexes.

A set of experiments in surface-initiated ring-opening metathesis polymerization, including end-functionalization of growing brushes and contact angle/cyclic voltammetry measurements. We report preparation and CV of two different conjugated polymer films, and several endgroup and sidechain functionalization experiments using cross-metathesis and active ester substitution.<br>
