| Abstract: | Novel extremely oxygen sensitive (many pyrophoric) alkoxides of Cr(II) were prepared by alcoholysis of Cr[N(SiMe3)2]2LL′, where L, L′ = ether, THF, or Py. They were characterized by elemental analyses, reflectance spectroscoppy, solubility, and chemical behavior. Solubility of the alkoxides is influenced most by drying conditions. Thoroughly dried aliphatic products are quite insoluble and exhibit coordinations polymer characteristics. Sterically hindered alkoxides are less associated, more soluble in general, and tend to form crystalline adducts with donor ligands. Primary alcohols (except MeOH) gave yellow/brown, secondary alcohols purple/violet and tertiary alcohols (as well as many phenols) blue derivatives. Some chemical reactions of selected alkoxides are discussed. |
