process to achieve hexadeca - save - trimetilacetato (a, a ') - octa - save octacrom carbons (iii)

摘要

the invention relates to processes to achieve compusilor coordinativi polinucleari, in particular compusilor of cr (iii) with properties of molecular magnets. the process to achieve hexadeca - (- trimetilacetato (a, a ') - octa - (octacrom carbons (iii) provides interaction in a teflon vessel cristalohidratului fluoride of cr (iii) in dimethyl sulfoxide trimetilacetic with acid at a temperature of 140.160u00b0c for three five hours, separation and purification of the product obtained. carrying out the reaction in a glass vessel leads to a sudden drop of the yield of the product. the proposed process allows increasing reaction efficiency to 60 80% in comparison with the known 20 30%. u0155
