Transition-Metal-Substituted Diphosphenes, XXIII. -Studies on the Synthesis and Reactivity of Dihalophosphido Complexes of Iron and Ruthenium(η5-C5Me5)(CO)2FeP(SiMe3)2 (1a) reacts with two equivalents of C2Cl6 to give the dichlorophosphido complex (η5-C5Me5)-(CO)2FePCl2 (2a). The latter is easily converted into (η5-C5Me5)(CO)2FeP(—E)Cl2 (3; E=S; 4: E=Se) by treatment with the respective chalcogen. The reaction of 1a with 2a leads to a mixture of the cyclotriphosphane [(η5-C5Me5)-(CO)2FeP]3 (8a) and the bicyclo[1.1.0]tetraphosphane [(η5-C5Me5)(CO)2FeP)2P2(10). The same result is obtained when 1a is treated with only one equivalent of C2Cl6. In addition the dihalophosphido complexes (η5-C5Me5)(CO)2RuPCl2 (2c), (η5-C5H5)(CO)(PPh3)FePCl2 (2b), (η5-C5Me5)(CO)2FePBr2 (2d), and (η5-C5Me5)(CO)2FePI2 (2e), and the cyclotriphosphane [(η5-C5Me5)(CO)2RuP]3 are synthesized.
