Carboranes as Ligands for the Preparation of Organometallic Tc and Re Radiopharmaceuticals. Synthesis of [M(CO)3(η5-2,3-C2B9H11)]- and r ac-[M(CO)3(η5-2-R-2,3-C2B9H10)]- (M = Re, 99Tc; R = CH2CH2CO2H) from [M(CO)3Br3]2-
Abstract
A new and high yielding method for the synthesis of [M(CO)(3)(eta(5)-2,3-C(2)B(9)H(11))](-) and the bifunctional metal complexes, rac-[M(CO)(3)(eta(5)-2-R-2,3-C(2)B(9)H(10))](-) (R = CH(2)CH(2)CO(2)H), from [M(CO)(3)Br(3)](2)(-) (M = Re, (99)Tc) was developed. The general approach entailed the addition of nido-[(C(2)B(9)H(12))(-)], or the acid substituted analogue, to [M(CO)(3)Br(3)](2)(-) (M = Re, (99)Tc) in the presence of TlOEt in THF. It …
