Compound (ν5-C5Me5)(CO)(NO)ReBr (3), generated from 5-C5Me5)(CO)2(NO)Re>BF4 and (Bu4N)Br, reacts with LiP(SiMe3)2 to give the disilylphosphido complex (ν5-C5Me5)(CO)(NO)ReP(SiMe3)2 (4).Complex 4 is converted into the diphosphenyl complex (ν5-C5Me5)(CO)(NO)Re-P=P-C6H2(tBu)3-(2,4,6) (5) by treatment with 2,4,6-(tBu)3C6H2PCl2.The reaction of 5, which is stable in solution, with Cr(CO)3 affords stable (ν5-C5Me5)(CO)(NO)ReP=P-C6H2(tBu)3-(2,4,6) (7).For comparison, the complexes (ν5-C5Me5(CO)(NO)MnP=P-C6H2(tBu)3-(2,4,6) (9) and (ν5-C5Me5)(CO)2 FeP=P-C6H2(tBu)3-(2,4,6) (10) were synthesized as well.Compound 10 was characterized by an X-ray structure analysis.
