    摘要:
    Treatment of anionic acetylide complexes [(eta(5)-C5H5)(NO)(CO)WC=CR](-)[R=Si(CH3)(3) (3), C(CH3)(3) (11a), or C6H5 (11b)] with allylic iodides 4b, 14, methallyl iodide, and 3-iodocyclohexene in THF at 0 degrees C afforded the corresponding eta(1)-alkynyl-eta(3)-allyl complexes 5/6, 12/13, and 15-19. The formation of these eta(3)-allyl complexes is rationalized by the electrophilic attack on the metal center of acetylide complexes to create a eta(1)-allyl complex, which is further stabilized by elimination of a CO ligand. The eta(3)-allyl complexes 12a/13a, 12b/13b, 18a, and 19a undergo a surface-catalyzed isomerization on silica gel as well as neutral alumina to the (eta(2)-allene)tungsten complexes 20-23. The crystal structures of complexes 17b and 20 are reported.

    The reaction of vinylidene complexes [(η5-C5H5)(CO)(NO)WCCHR] [R = H (1a), CH3 (1b), C6H5 (1c)] with chlorodiphenylphosphine (2) leads to neutral [R = H (3a), CH3 (3b), C6H5 (3c)]. Analogously the reaction of chlorodi-tert-butylphosphine (4) with [(η5-C5H5)(CO)(NO)WCCH2] (1a) gives rise to chloro(η5-cyclopentadienyl)nitrosyl(η2-di-tert-butylphosphinovinyl)tungsten (5).
