Solutions of tris(acetylacetonato)zirconium chloride, bis(acetylacetonato)zir-conium dichloride, tetrakis(acetylacetonato)zirconium, zirconium tetraacetate, or zirconium tetranitrate, all reduced with triethylaluminum in hexamethyl-phosphoramide, are said to lead to high molecular weight products [41]. Unfortunately, the solvent is no longer available because of its carcinogenicity. Perhaps such alternate solvents as formamide, dimethylformamide, dimethyl-sulfoxide, and acetonitrile should be investigated.

Other useful organometallic reagents for the preparation of tertiary stibines or related heterocyclic compounds are compounds of lithium, aluminum, tin, copper, zirconium, and other metals. " In most cases, these metal compounds are reacted with antimony chlorides or bromides. Good yields of tertiary stibines were, however, also obtained by the interaction (equation 3) of triaUcylaluminium reagents and tris(dimethylamino)stibine. ...

Enones are reduced to saturated ketones by catalytic hydrogenation provided the reaction is stopped following the absorption of 1 mol of hydrogen. " A number of catalysts were found useful for this, including platinum, platinum oxide,Pt/C, " Pd/C, - Rh/C, " tris(triphenylphosphine)rhodium chloride, - nickel-aluminum alloy in 10% aqueous NaOH, and zinc-reduced nickel in an aqueous medium. Mesityl oxide is formed from acetone and reduced in a single pot to methyl isobutyl ketone using a bifunctional catalyst which comprised palladium and zirconium phosphate (Scheme 20). 

The crystal structure of [(f-Bu3-CO)2ZrCl3 Li(OEt2)2] (295) is shown in Fig. 42, and consists of two chloride groups bridging lithium and zirconium atoms. The overall stereochemistry of the zirconium center is pseudotrigonal bipyr-amidal and the bulky tri-fm-butylmethoxide ligands occupy the least-crowded equatorial sites. 

Similarly, scandium triflate (Sc(OTf)3), zirconium triflate (Zr(OTf)4) and titanium chloro(tris)triflate (TiCl(OTf)3) were also used for the orf/zo-acylation of phenols and 1-naphthols using acid chlorides . ...
