Organometallic Hydroxides & Oxides - Alfa Aesar

Organometallic Hydroxides & Oxides

Organometallic hydroxides contain a hydroxyl group attached to one or more metal atoms of organometallic compounds. The preparation of soluble organometallic hydroxides is a key step in the preparation of organometallic oxides containing the heterobimetallic M-O-M' unit. For a comprehensive review of transition-meal based organometallic hydroxides, see: Roesky, H. W.; Singh, S.; Yusuff, K. K. M.; Maguire, J. A.; Hosmane, N. S. Organometallic Hydroxides of Transition Elements”. Chem. Rev. 2006, 106, 3813-3843. Owing to the tendency of the OH moiety to act as a bridging group, many of them are dimeric, although trimers and tetramers are reported.

The reactions of Cp3Ln (Ln = Yb, Dy, Er, Sm) with several hydroxides to yield compounds with the skeletons M(mu-O)Ln and M(mu-OH)Ln are reported (see: Roesky, W. “Preparation of Organometallic Hydroxides and their Reactions with Lanthanide Compounds”. Z. anorg. allg. Chem. 2010, 636, 2192-2197). Main group monomeric hydroxides, containing terminal -OH groups are utilized to synthesize the desired lanthanide-main group hetero-bimetallic systems containing a Ln-O-Al arrangement. These compounds are useful as catalysts in epsilon-caprolactone polymerization.

Organotitanium and organozirconium compounds are useful as catalysts in the polymerization of olefins and in the chemical fixation of nitrogen. Organometallic hydroxides may also find application in organometallic crystal engineering. A judicious choice of the building blocks may yield materials with attractive magnetic, conducting, superconducting, and nonlinear optical properties.

Tetraalkyl-1,3-diacetoxydistannoxanes, such as bis(acetoxydimethyltin)oxide, are effective in catalytic quantities for esterification and trans-esterification reactions using monohydric alcohols and diols other than 1,2-, and 1,3-diols. The reaction works well in non-polar solvents and halocarbons. These compounds are exceptionally good catalysts for the isocyanate-hydroxyl reaction. Since the tetraalkyl-1,3-diacetoxy-distannoxanes are effective in a neutral medium, corrosion is minimized during manufacturing unlike under the usual acidic and basic conditions.
