Phosphanediyl transfer from inversely polarized phosphaalkenes (RP)-P-1=C(NMe2)(2) (R-1 = t-Bu, Cy, Ph, H) onto phosphenium complexes [(η5-C5H5)(CO)(2)M = P(R-2)R-3] (R-2 = R-3 = Ph; R-2 = t-Bu, R-3 = H; R-2 = Ph, R-3 = N(SiMe3)(2))
Abstract
Reaction of the freshly prepared phosphenium tungsten complex [(eta(5)-C5H5)(Co)(2)W=PPh2] (3) with the inversely polarized phosphaalkenes RP=C(NMe2)(2) (1) (a: R = tBu; b: Cy; c: Ph) led to the eta(2)-diphosphanyl complexes [(eta(5)-C5H5)(CO)(2)W-P(R)-PPh2] (9a-c) which were isolated by column chromatography as yellow crystals in 24-30 % yield. Similarly, phosphenium complexes [(eta(5)-C5H5)(Co)(2)M=P(H)tBu] (M = W (6); Mo (8)) were converted into [(eta(5)-C5H5)(CO)(2)MP(t-B-u)P(H)tBu] (M = W (11); Mo (12)) by the formal abstraction of the phosphanediyl [PtBu] from 1a. Treatment of [(eta(5)-C5H5)(CO)(2)W=P(Ph)N(SiMe3)(2)] (4) with HP= C(NMe2)(2) (1d) gave rise to the formation of yellow crystalline [eta(5)'-C5H5)(CO)(2)W-P(H)-(Ph)N(SiMe3)(2)] (10). The products were characterized by elemental analyses and spectra (IR, H-1, C-13-, P-31-NMR, MS). The molecular structure of compound 10 was elucidated by an X-ray diffraction analysis.
