Abstract
Ferrocenium hexafluorophosphate reacts with aminophosphines P(NEt2)3, PhP(NEt2)2, Ph2P(NEt2), CyP(NEt2)2, and Pri2P(NEt2) to form ferrocenylphosphonium salts [(C5H5)-Fe(C5H4PRR′R″)](PF6), ferrocene, and [HPRR′R″](PF6). The theoretical analysis of the reactions (M06-L/6-311++G(d,p)) showed that these reactions involve a sequence of the following steps: the addition of phosphine to the cyclopentadienyl ring, the oxidation of the initial adduct by the starting ferrocenium to give a dicationic η4-phosphocyclopentadiene complex with an agostic $$C_{sp^{3}}-H\rightarrow{Fe}$$ bond, and the deprotonation of this bond to form ferrocenylphosphonium salts. The resulting ferrocenylphosphonium salts are resistant to alcoholysis and do not react with carbon disulfide.
