Abstract:
This thesis concerns the synthesis and the structural characterization of
organometallic complexes inspired by the active site of [Fe-Fe] hydrogenases.
During this work, we have obtained:
Two binuclear hexacarbonyl complexes resulting from the reaction of
nonacarbonyl iron Fe2(CO)9 on the phenyldithiobenzoate and 1,2-
dithiolene respectively:
- (µ-η2PhC(S)=C(S)Ph)Fe2(CO)6 1
- (µ-(o)SPhS-)Fe2(CO)6 2
Three complexes resulting from the substitution reaction of carbonyls by
P(OMe)3 in complex 1:
- (µPhC(S)=C(S)Ph)Fe2(CO)4[P(OMe)3]21a.
- (η2PhC(S)=C(S)Ph)Fe(CO)[P(OMe)3]21b.
- (µ-PhC(S)=C(S)Ph)Fe2(CO)5[P(OMe)3] 1c.
Two complexes resulting from the reaction of carbonyl substitution by
(Me)2PhNC in complex 2:
- (-(o)SPhS-)Fe2(CO)5[(Me)2PhNC] 2a.
- (-(o)SPhS-)Fe2(CO)4[(Me)2PhNC]2 2b.
The structural study of complexes 1, 1a, 2 and 2a shows that they are structural
models of [Fe-Fe] hydrogenases.
