Reactions of Ferrocenium Hexafluorophosphate with P?OR Nucleophiles Give Ring C?H Functionalization or Ring Replacement Products Depending on the Phosphorus Reagent

Ferrocenium hexafluorophosphate reacts with different P?OR nucleophiles (PR3) in CH2Cl2 at room temperature to give either half-sandwich complexes [CpFe(PR3)3](PF6) (PR3=P(OMe)3, P(OEt)3, PhP(OMe)2) or ferrocenylphosphonium salts [CpFe(C5H4PR3)](PF6) (PR3=iPr2P(OMe), iPr2P(OEt)). Mixtures of both products are formed for some other nucleophiles (PR3=Ph2P(OMe), Ph2P(OEt), PhP(OiPr)2). The mechanism of the former reaction was established using DFT calculations. This reaction pathway is especially characteristic of π-acceptor nucleophiles, which is presumably explained by their ability to stabilize the 19e intermediates. The result of the reaction with tertiary phosphines, aminophosphines, and P?OR nucleophiles can be reliably predicted based on the values of the Tolman electronic parameter (below 2070 cm?1 – only ferrocenylphosphonium salt, in between 2073 cm?1 and 2080 cm?1 – only half-sandwich complex, and in the range from 2070 cm?1 to 2073 cm?1 – mixtures of both products).

LES PHOSPHORANES MONOCYCLIQUES A LIAISON PH DANS LES REACTIONS DE REDISTRIBUTION DE LIGANDS DES COMPOSES DU PHOSPHORE TRICOORDONNE

The oxidative addition of alcohols and amines with 2-alkyl, 2-aryl, 1,3,2-dioxa, oxaza or diazaphospholanes, leads to a ring opening reaction and ligands exchange around the phosphorus atom by alcoholysis or aminolysis of P-O or P-N bonds.In nearly all cases, monocyclic phosphoranes with P-H bond have been detected in an intermediate step during the exchange of one tricoordinate form to another one.At last we have discussed the phorpholanyl ring stability. - Key words: 1,3,2-Dioxaphospholanes; 1,3,2-oxaza-phospholanes; 1,3,2-diazaphospholanes; Monocyclic phosphoranes with P-M bonds; phosphoranyl ring stability.
