文摘
Chemical reduction of [Mo2Cp2(
-Cl)(-PA2)(CO)2] (A = Cy, Ph, OEt) gives the correspondingalkaline metal salts of the triply bonded anions [Mo2Cp2(-PA2)(-CO)2]-, which exhibit both molybdenumand oxygen nucleophilic sites. The PCy2 anion reactseasily with NH4+, [AuCl(PR3)], or MeI to give unsaturated dicarbonyls [Mo2Cp2(-X)(-PA2)(CO)2] (X = H,AuPR3, Me), while [Me3O]BF4 gives the methoxycarbyne[Mo2Cp2(-COMe)(-PCy2)(-CO)] and allyl chloride rearranges to give the unsaturated alkenyl complex [Mo2Cp2(-PCy2)(-CMeCH2)(CO)2].
