Catalytic wittig reactions of semi- and nonstabilized ylides enabled by ylide tuning

The first examples of catalytic Wittig reactions with semistabilized and nonstabilized ylides are reported. These reactions were enabled by utilization of a masked base, sodium tert-butyl carbonate, and/or ylide tuning. The acidity of the ylide-forming proton was tuned by varying the electron density at the phosphorus center in the precatalyst, thus facilitating the use of relatively mild bases. Steric modification of the precatalyst structure resulted in significant enhancement of E selectivity up to >95:5, E/Z. Time for a tune up: Catalytic Wittig reactions with semi- and nonstabilized ylides were enabled by use of a masked base (NaOCO2tBu) and/or ylide tuning. The acidity of the ylide-forming proton was tuned by varying the electron density at the P center in the precatalyst, thus facilitating the use of relatively mild bases. Steric modification of the precatalyst structure resulted in significant enhancement of E selectivity.

COMPARATIVE STUDIES ON SYNTHESIS AND PROPERTIES OF PHOSPHORUS AND SULFUR HETEROCYCLES: THE HETERONIN OXIDE SYSTEM

Phosphonin oxides are the first recognizable product on reaction of 9-phosphabicyclonona-2,4,6-trienes with peroxides at -15 deg C. These compounds (R=C6H5 or t-C4H9) are stable below -15 deg C, but undergo intramolecular cycloaddition to

Reactions of Magnesium-Cyclooctatetraene with Dichlorophosphanes: Characterization and Rearrangements

The reaction of magnesium-cyclooctatetraene (MgCOT) with dichlorophosphanes RPCl2 (R = tert-butyl, cyclohexyl, menthyl) yields 9-phosphabicyclononatrienes 1b-d, which thermally rearrange to syn-9-phosphabicyclononatrienes 2b-d.However, 1b an
