- Oxidative Cross-Coupling of Boron and Antimony Nucleophiles via Palladium(I)
-
The use of an isolatable, monomeric Pd(I) complex as a catalyst for the oxidative cross-coupling of aryl-antimony and aryl-boron nucleophiles is reported. This reaction tolerates a wide variety of substrates, with >20:1 selectivity for cross-coupled products. This strategy offers a new approach to achieving the selective cross-coupling of nucleophiles.

Exchange reactions of R3Sb (R = o-Tol, m-Tol, p-Tol) with SbCl3 in a 1:2 molar ratio give RSbCl2.Silylstibanes RSb(SiMe3)2 were obtained by reaction of RSbCl2 and Me3SiCl with Mg in THF.Slow access of air to solutions of RSb(SiMe3)2 afforded orange crystals of the composition (RSb)n.Crystal structures were determined by X-ray crystallography fro R = o-Tol and m-Tol as stacks of (RSb)6 rings in the chair conformation with equatorial substituents.In the crystals of (m-TolSb)6 there are short intermolecular Sb***Sb distances of 420 pm.Solutions of (RSb)n (R = Ph, o-Tol, m-Tol, p-Tol) in C6D6 were analyzed by 1H-NMR spectroscopy.They contain (RSb)5 and (RSb)4 in equilibria.Raman spectra of (PhSb)6 or (p-TolSb)n show signals for Sbn at = 151 or 153 cm-1. 13C-CP-MAS-NMR data of (p-TolSb)n are reported. - Key Words: Cyclopentastibanes/ Cyclohexastibanes/ Antimony compounds/ Phenylantimony rings
