摘要 |
FIELD: chemistry of oxoalkoxo complexes of metals holding the greatest promise for production of oxide and metallic materials. SUBSTANCE: proposed method provides for increased yield of products at synthesis of oxomethylate complexes at common formula M4O2(OCH3)14(ReO4)2 or M2(OCH3)8(ReO4)2 (where M is Nb, Ta) by interaction of powder-like rhenium oxide (VII) Re2O7 with niobium methylates Nb2(OCH3)10 and/or tantalum methylates Ta2(OCH3)10 in form of solutions in dehydrated toluene at the following heating modes: 1) keeping the reagents at room temperature after mixing for at least 3 min at continuous mixing; 2) keeping the reagents at temperature of 29-38 C for 30-60 min at continuous mixing; 3) boiling for 5-20 min. After cooling, yield of target products reaches 93% (relative to introduced Re2O7). EFFECT: enhanced efficiency. 6 ex |
