Transition-Metal-Substituted Diphosphenes. XIX. - On the Reactivity of Disilylphosphido Iron Complexes towards 2,4.6-(CF3)3C6H2PCl2 and 2.6-(CF3)2C6H3PCl2. Diphosphenyl Complexes with Fluoroaryl Substituents(η5-C5Me5)(CO)2Fe—P(SiMe3)2 (2a) and (η5-C5H5)(CO)(PPh3)-Fe—P(SiMe3)2 (2c) react with ArylPCl2 [3a: Aryl = 2,4,6-(CF)3-C6H2; b: Aryl = 2,6-(CF)2C6H3] to yield the thermolabile diphosphenyl complexes (η5-C5Me5)(CO)2Fe—P=P-Aryl (4a,b) and (η5-C5H5)(CO)(PPh3)Fe—P=P-Aryl (4c,d), respectively. The isolation of the pure compounds 4a-d failed. They are, however, intercepted as their (CO)5Cr adducts 5a-d by treatment with [(Z)-cyclooctene]Cr(CO)5- Complex (η5C5Me5)(CO)2Fe—P[Cr(CO)5]= P-C6H2(CF3)3-(2,4,6) (5a) is characterized by single-crystal X-ray diffraction analysis.
