Autor: J. D. Foulon, Nadine Hovnanian, Gisèle Foulon

Publikováno v: Polyhedron. 12:2507-2511

The reaction between VOCl3 and 3 equivalents of sodium 1-methoxy-2-propanoxide in a mixture of toluene/1-methoxy-2-propanol leads, after removal of the salt and crystallization of the concentrated filtrate, to a vanadium(IV) compound which has been c

Publikováno v: Inorganica Chimica Acta. 209:47-53

Y(thd)3(H2O) (I) has been prepared from yttrium nitrate via the aqueous method; its drying yielded Y(thd)3 (III). The sublimation of compound II, resulting from the reaction of yttrium isopropoxide with thdH, also yielded Y(thd)3. Compounds II and Il

Synthesis and x-ray crystal structure of a mononuclear aryloxide-crown ether of barium: [Ba(OAr)2(18-crown-6)] · (2ArOH)(18-crown-6) (Ar = C6H3But2-3,5)

Autor: Louis Cot, Philippe Miele, Nadine Hovnanian, J. D. Foulon

Publikováno v: Polyhedron. 12:267-271

The reaction of elemental barium with 3,5-di-tert-butylphenol and 18-crown-6 in THF at reflux temperature and/or using gaseous ammonia as catalyst yields a monomeric barium compound. The complex has been characterized by IR, 1 H NMR, mass spectroscop
