New ferrocenylalkylimidazolium salts [Fc (CH2) n (C3H3N2) R] X− were synthesised through the incorporation of green chemistry principles of atom economy and when feasible under solvent-free conditions. The products comprise a series of salts all characterised by the ferrocenyl moiety with variations in the length of the linker alkyl chain (n), the size of the imidazolium alkyl substituent (R) or the electronic nature of the counter-ion (X−). The ...
