“…Combustion analyses (C, H) were performed at in‐house facilities with an Elementar Analyzer Vario MICRO Cube from Heraeus. HRuCl(CO)(P i Pr 3 ) 2 [19b] and (4‐ethynylphenyl)ferrocene were prepared according to literature methods. Single crystals suitable for X‐ray crystallography were grown by layering a saturated CH 2 Cl 2 solution of the respective complex with methanol to yield dark‐red ( 1 and 2 ‐acac) or black ( 2 ‐hfac) platelike crystals.…”

“…In the first step of this synthesis (Scheme 2), we prepared ferrocenylacetophenones 3a-c by coupling of ferrocene with the appropriate diazonium salts 2a-c, obtained by diazotation of the corresponding aminoacetophenones 1a-c, as described elsewhere [21][22][23]. Methylketones 3a-c were treated with phenylhydrazine to give the corresponding hydrazones 4a-c.…”

“…[290] Viele Ansätze umfassen den Einsatz von Acetophenon als Ausgangsverbindung sowie die Umwandlung von Aldehyden in terminale Alkine durch Vilsmeier-und Wittig-Reaktionen oder die Dehydratisierung von Acetylferrocenen. [291] Ein direkter Zugang ist die Kupplung von Ferrocen mit einem terminalen Alkin in einer Eintopfreaktion mit DiazotierungArylierung (Schema 63).…”

“…1,2-Alkinylierte Ferrocene [292] sind anders als 1,1'-Diethinylferrocen (Bildung von ansa-Ferrocenen) [293] halbwegs stabil. Als wertvoll für die Synthese erwiesen sich die stufenweise Umwandlung funktionaler Substituenten durch ortho-Lithiierung (LDA) von Bromferrocen [294] und die Stannylierung von Diethinylferrocenen [295] sowie der Einsatz von halbmaskierten Acetyl-oder Formylferrocenyl-substituierten Alkinen [290,296] (Schema 64). Ferrocenylalkine wurden durch Pd-katalysierte Polykondensation von 1,1'-Dihalogenferrocenen mit terminalen Alkinen [297,298] oder Trimethylstannyl-stabilisierten Verbindungen in Polymere eingebaut (Schema 65).…”
