Ferrocene

New 1,2-disubstituted ferrocenyl stibines containing N-heterocyclic pendant arm: Sb–N hypervalent compounds

“…Also there appears only one report on the one-pot alkylation of [1-N,N-dimethylaminomethyl-2-diphenylphosphino]ferrocene (1b) with benzyl bromide and subsequent replacement of the ammonium group with a nucleophile [19] but on the other hand, reaction of ferrocenyl phosphine (1b) with 1 equiv. of methyl iodide gives preferably an unstable N-methylated product, which further reacts with O-and N-nucleophiles in a manner analogous to that for the nonphosphinylated salt [FcCH 2 NMe 3 ]I, [20,21]. Reaction of 1b with excess of MeI yields the respective P,N-dimethylated salt.…”

First ferrocenylstibines and their molecular structures

“…It is to be noted that phosphorus analogue of (1) reacts with one equivalent of MeI and give an unstable N-methylated product while with an excess of MeI yields the respective P,N-dimethylated salt [21,22], which in different to the case of antimony where with one or more equivalent of MeI, a very stable N-methylated product was obtained.…”
