proceed via ferrocenylmethylcarbene, and afford similar reaction products. In these reactions, a preferred addition reaction of the carbene to vinylferrocene is noticed. In this connection, the competitive reactivities of vinylferrocene, styrene, p-methoxystyrene and cyclohexene towards dichlorocarbene and diphenylcarbene have been measured.
Abstract An improved, short and efficient synthesis of vinylferrocene is reported. This three-step synthesis includes Friedel–Crafts acylation, reduction, and a one-pot mesylation/elimination step to afford the target compound in 62% yield over three steps. An improved, short and efficient synthesis of vinylferrocene is reported. This three-step synthesis includes Friedel–Crafts acylation, reduction
