Synthesis of secondary allenylidene-molybdenum complexes with a ferrocenyl substituent from carbenium ions species stabilized by two organometallic moieties
摘要:
The monoallenylidene complex [Cp(2)Mo(2)(CO)(4){mu-sigma:eta(2)-C=C-C(Fc)(H)}] (5) and the diallenylidene complex [{Cp(2)Mo(2)(CO)(4)(mu-sigma:eta(2)-C=C=C(H))}(2)Fc] (6) have been obtained from the corresponding monocarbenium ion [Cp(2)Mo(2)(CO)(4){mu-eta(2):eta(3)-HC=C-C(H)(Fc)}][BF4] (3) and the dicarbenium ion [{Cp(2)Mo(2)(CO)(4)(mu-eta(2):eta(3)-HC=C-C(H)}(2)Fc][(BF4)(2)] (4) respectively, and their spectroscopic data are determined.
