Zusammenfassung
Silica-induced elimination of dimethylamide from [(CO)5M(CC)3C(NMe2)3]- [M = Cr (4a), W (4b)] affords the first isolated and characterized heptahexaenylidene complexes [(CO)5 M=C=C=C=C=C=C=C(NMe2)2] (5a,b). Complexes 4a,b were generated by sequential reaction of Me3Si(CC)3SiMe3 with LiMe•LiBr, [(Me2N)3C]+Cl-, LiBu, and [(CO)5M(thf)]. Complex 5b is inert in methanol, but adds dimethylamine across the C5=C6 bond to give [(CO)5W=C=C=C=C=C{CH=C(NMe2)2}NMe2]. The reaction of 5a,b with LiMe•LiBr and SiO2 generates the heptahexaenylidene complexes [(CO)5M=C=C=C=C=C=C=C(Me)NMe2] (8a,b). Trapping of 8b with HNMe2yields pentatetraenylidene complex [(CO)5W=C=C=C=C=C{CH=C(Me)NMe2}NMe2].
