摘要:
The reaction of the hetero-ring anion [(C2Bu2P2Sb)-P-t](-) with [{M(eta(4)-1,5-C8H12)Cl}(2)], M = Rh, Ir, leads to the formation of [M((eta(5)-(C2Bu2P2Sb)-P-t)N eta(4)-1,5-C8H12)], M = Rh 7, Ir 8. Treatment of CoCl2 with either an equimolar mixture of a [(C2Bu2P2Sb)-P-t](-) [C5Me5](-), or two equivalents of [(C2Bu2P2Sb)-P-t](-) affords the compounds [Co(eta(5)-C5Me5)(eta(4)-(C2Bu2HP2Sb)-H-t)], 11, and [Co(eta(5)- (C2Bu2P2Sb)-P-t)(eta(4)-(C2Bu2HP2Sb)-H-t)], 12, which represent the first examples of diphosphastibacyclopentadiene complexes; the X-ray crystal structures of 7 and 11 are reported.
