Scope and limitations of the Peterson olefination reaction as a route to vinylidene phosphanes

The Peterson olefination reaction has been investigated as a route to novel P-substituted alkenes. The reaction between [(nPr2P) 2(Me3Si)C]Li and paraformaldehyde cleanly gives the symmetrical vinylidene phosphane (nPr2P)2C=CH2 (4) in good to excellent yields. In contrast, reactions between [(R 2P)(Me3Si)2C]Li (R = Me, nPr) and paraformaldehyde yield complex mixtures of products which do not contain the expected vinylidene species. However, the unsymmetrical vinylidene phosphanes [nPr2P(BH3)](Me3Si)C=CH2 (6), (Ph2P)(iPr2P)C=CH2 (7), [nPr 2P(S)](Me3Si)C=CH2 (10), [Ph 2P(S)][iPr2P(S)]C=CH2 (11) and [Ph 2P(S)][Me2P(S)]C=CH2 (12) are readily accessible by the Peterson olefination reaction {compound 7 is obtained by deprotection of the corresponding borane adduct [Ph2P(BH 3)][iPr2P(BH3)]C=CH2 with pyrrolidine}.

Transition Metal Complexes of Instable Ylides, III. Preparative, Stereochemical, and Mechanistic Aspects of the Stabilization of Instable Ylidic Chelate Ligands by Coordination to Chromium

The sulfur ylide complex (CO)5Cr (1) reacts with unsymmetrically substituted diphosphanes and arsanes of the type R21E1CH2E2R22 (4a-d) to give regioselectively the chelate complexes 5a-d.In 5 the more nucleophilic end of 4 is transformed to the onium centre.On the other hand, (CO)4Cr2 (2) and 4a-d produce regioselectively the isomeric chelate complexes 6a-d, in which the more nucleophilic donor function of 4 is ligated to the chromium atom.

Unsymmetrical bis-phosphorus ligands. 9. Group 6 metal carbonyl complexes and other derivatives of various (phosphinomethyl)phosphine sulfides

Some chemistry of a new class of compounds, (phosphinomethyl)phosphine sulfides, Ph2P(S)CH2PR1R2, is described. Reaction with sulfur gives disulfides, Ph2P(S)CH2P(S)R1R2, with sodium gives unsymmetrical di(tertiary phosphines), Ph2PCH2PR1R2, with alkyl halides gives phosphonium salts, [Ph2P(S)CH2PR1R2R3]X, and with group 6 metal carbonyls gives a complex with phosphorus and sulfur bonded to the metal in a five-membered chelate ring, [Ph2P(S)CH2PR1R2]M(CO)4; heating causes the sulfur to transfer to the more basic phosphorus atom, producing Ph2PCH2P(S)R1R2. Extensive phosphorus and proton NMR data are given.
