Abstract
The vinyliminium complex [Fe2{mu-eta1:eta3-C(SiMe3)=CHC=N(Me)2}(-CO)(CO)(Cp)2][SO3CF3] reacts with HCCR (R = CPh2OH), affording a mixture of the 2,4,6 trisubstituted oxo-5-cyclohexadienyl complex [Fe(5-C6H2O(NMe2)(SiMe3)(R)], the 2,6-disubstituted phenol C6H3R (NMe2)OH (R = CHPh2) and 1,2,4 trisubstituted ferrocene [1-NMe2-2-R-4-SiMe3-Fc]. The corresponding reaction with HCCR (R = CMe2OH) yields analogous products: [Fe(5C6H2O(NMe2)(SiMe3)R] (R′ = CMe=CH2), the phenol C6H3R′(NMe2)OH togheter with [1-NMe2-2-R-4- SiMe3-Fc].I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
