Reactions of chromium(III) and cobalt (III) tris(3-bromo-2,4-pentandionates) with sodium dibutyl phosphate, sodium dibutylphosphinate, sodium dibutyl dithiophosphate, and sodium dibutyldithiophosphinate were studied. Oxygen-containing derivatives of phosphorus acids give metal polyphosphates and polyphosphonates, and in the case of sodium dibutyl phosphate, a bromine substitution product was isolated in 3% yield. The reactions of the chelates with sodium dibutyl dithiophosphate and sodium dibutyldithiophosphinate, substitution products were isolated in 54% and 65% yields, respectively. The reactions all involved reductive dehalogenation along with substitution.
对铬(III)和钴(III)三(3-溴-2,4-戊二酮酸盐)与二丁基磷酸钠、二丁基磷酸盐钠、二丁基二硫代磷酸钠和二丁基二硫代磷酸盐钠的反应进行了研究。含氧的磷酸衍生物会形成金属多磷酸盐和多磷酸酯,在二丁基磷酸钠的情况下,得到了一种溴的取代产物,产率为3%。与二丁基二硫代磷酸钠和二丁基二硫代磷酸盐钠的螯合物反应中,分别获得了54%和65%的取代产物。这些反应都涉及到还原去卤素化和取代反应。
