Preparation and characterization of PdII-ylide complexes of type 3-2-XC3H4)>BF4 (X=H, Me; R=p-C6H4OMe, C(Me)3, Me, C6H11, p-c6H4NO2). Crystal structure of (η3-2-MeC3H4)>BF4

Seven compounds of general formula 3-2-XC3H4)>BF4 (X=H, R=p-C6H4OMe (1), R=C(Me)3 (2); X=Me, R=p-C6H4OMe (3), C(Me)3 (4), Me (5), C6H11 (6), p-C6H4NO2 (7)) have been prepared by chloride abstraction from PdCl(η3-2-XC3H4) (X=H, Me) with AgBF4 and subsequent reaction of the cationic intermediate with the appropriate isocyanide ligand.All the complexes have been characterized by analitical and spectroscopic (IR, 1H and 31P NMR) data.They have been shown to be mixture of two diastereoisomeric forms arising from the simultaneous presence on the palladium atom of the asymmetric ylidic carbon atom and the η3-allyl ligand.The determination of the crystal structure of complex 4 showed that in the solid state only diastereoisomer is present.The crystals are monoclinic, space group Pc with a 9.833(3), b 14.383(4), c 11.762(4) Angstroem, β 114.68(3) deg, and Z=2.Final full-matrix least-squares refinement, based on 2413 reflections, convergated to R=0.050.The keto-stabilized ylide ligand is C bonded to the metal with a Pd-C distance of 2.175(9) Angstroem.

A Study Directed to the Asymmetric Synthesis of the Antineoplastic Macrolide Acutiphycin under Enantioselective Acyclic Stereoselection Based on Chiral Oxazaborolidinone-Promoted Asymmetic Aldol Reactions

Reactions with Phosphine Alkylenes, XLV. Reactions of Alkylidenetriphenylphosphoranes with Tetramethylformamidinium Chloride. Synthesis of triphenylphosphonium Chloride and (Formylalkylidene)triphenylphosphoranes

Phosphonium ylides 1 react with tetramethylformamidinium chloride (2) to form enamine phosphonium chlorides 8 and the formic orthoamide 7.The salts 8 show temperature depending 1H NMR spectra with respect to the protons of the dimethylamino group (hindered rotation around the C - N(CH3)2 bond).Treatment of 8 with acids and subsequently with bases gives rise to the formation of the formyl ylides 19. 8a is deprotonated with sodium amide to give the phosphaallene ylide 20, which reacts with water to yield the phosphane oxide 21, and with methyl iodide stereospecifically to form 8b.
