Zirconium(~v) carboxylates, Zr(OOCR)4 where R = Me, Et, CHZCl, CHCl, and CCI,, have been prepared by the reaction of zirconium(~v) chloride and carboxylic acids. The compounds have been characterized by elementary analyses, thermogravimetry and infrared spectral data. The compounds are non-electrolytes in nitrobenzene and probably have polymeric structures.

In Gegenwart von Dischwefeldichlorid ( ll) reagiert die Azoverbindung (I) bei der Photolyse zu Thiadiaziridin (III).

Durch Reaktion der Titelverbindungen (I) mit CIF (II) werden die Fluorsulfate (III) gewonnen; (IIIa) ist auch aus (Ia) mit XeF2 (V) zugänglich.

TiCl4 reagiert mit Ameisensäure bei tiefen Tempp.

Titanium(IV) chloride reacts with formic acid to give the disubstituted product, Cl2Ti(OOCH)2, at low temperatures and the hydrolysed product (OH)2Ti(OOCH)2 at higher temperatures. These compounds have been characterized by elementary analysis, infrared and thermal measurements. The possibility of these solvolysed products acting as Lewis acids has also been explored.
