Some aspects of home and heterometallic alkoxides based on functional alcohols

Functional alkoxides find applications in chemistry as catalysts or for organic synthesis as well as in material science. They can provide stabilization toward hydrolysis, reduce oligomerization and, thus, give access to volatility, act assembling ligands for the building up of mixed-metal species and to some extent control their stoichiometry. These aspects will be illustrated on non-silicon systems with alkoxide ligands bearing pendant ether, hydroxyl or amino functionalities, or unsaturated sites for organic cross-linking reactions. Fluoroalkoxides act often as functional groups via secondary M ... F bonds to electrophilic metals such as barium and will, thus, also be considered. (C) 1998 Elsevier Science S.A.
