Ferrocene melting point range
WebOct 9, 2024 · The compound was extremely stable, melting at 173 °C, sublimating under vacuum and being unaffected by boiling strong acids and strong alkalis. Pauson proposed the structural formula 3 (Fig. 1 ), which implied the formation of two intrinsically weak Fe–C σ … WebNov 17, 2024 · In this work, ferrocene, cobaltocene, and nickelocene were used as catalyst precursors. These metallocenes have similar melting points and relatively low sublimation temperatures (150–300 °C). Vapor pressure and their temperature dependencies seem important for application in the aerosol synthesis.
