- W2002967935 abstract "Bei der Reaktion äquimolarer Mengen an [(η5-C5Me5)(CO)2RuSb(SiMe3)2] (1 b) mit Carbonsäurechloriden RC(O)Cl (R = tBu, Ph, 1-Adamantyl) werden die Acyl(trimethylsilyl)stibanido-Komplexe [(η5-C5Me5) · (CO)2RuSb{C(O)R}(SiMe3)] 2 b (R = tBu), 4 b (R = Ph) und 6 b (R = 1-Ad) erhalten. Die Umsetzung von 1 b mit zwei Äquivalenten Pivaloylchlorid oder Benzoylchlorid liefert die Diacylstibanido-Komplexe [(η5-C5Me5)(CO)2Ru–Sb{C(O)R}2] (3 b, 5 b). Analog hierzu wird der Eisenkomplex [(η5-C5Me5)(CO)2FeSb(SiMe3)2] (1 a) von überschüssigem Säurechlorid in die entsprechenden Diacylstibanido-Komplexe 3 a (R = tBu), 5 a (R = Ph) und 7 a (R = 1-Ad) übergeführt. Die Reaktion äquimolarer Mengen 1 a mit RC(O)Cl führte lediglich zu Gemischen aus Mono- und Diacylstibanido-Komplexen neben unumgesetzten 1 a. Oxalylchlorid reagiert mit zwei Äquivalenten 1 a quantitativ zu [{(η5-C5Me5)(CO)2FeSb(SiMe3)C(O)}2] (8). Die Molekülstrukturen von 1 a, 2 b und 5 b wurden durch Röntgenstrukturanalysen bestimmt. Synthesis, Structure, and Reactivity of Functionalized Stibanido Complexes of Iron and Ruthenium [(η5-C5Me5)(CO)2MSbR1R2] (M = Fe, Ru; R1, R2 = SiMe3, C(O)tBu, C(O)Ph, C(O)-1 Ad) The reaction of equimolar amounts of [(η5-C5Me5)(CO)2RuSb(SiMe3)2] (1 b) and the carboxylic chlorides RC(O)Cl (R = tBu, Ph, 1-adamantyl) afforded the acyl(trimethylsilyl)stibanido complexes [(η5-C5Me5)(CO)2RuSb · {C(O)R}(SiMe3)] 2 b (R = tBu), 4 b (R = Ph), and 6 b (R = 1-Ad). The treatment of 1 b with two molar equivalents of pivaloyl chloride and benzoyl chloride led to the diacylstibanido complexes [(η5-C5Me5)(CO)2RuSb{C(O)R}2] (3 b, 5 b). Analogously, the iron complex [(η5-C5Me5)(CO)2FeSb · (SiMe3)2] (1 a) is converted into the corresponding diacylstibanido complexes 3 a (R = tBu), 5 a (R = Ph) and 7 a (R = 1-Ad) by an excess of acid chloride. The treatment of 1 a with equimolar amounts of RC(O)Cl gave inseparable mixtures of starting material and the monoacyl- and diacyl stibanido complexes. Oxalyl chloride reacted quantitatively with two equivalents of 1 a to give complex [{(η5-C5Me5) · (CO)2FeSb(SiMe3)C(O)}2] (8). The molecular structures of 1 a, 2 b and 5 b were elucidated by single crystal X-ray analyses." @default.
