资源简介：
A borate-containing
caged triarylphosphine L-X (X
= Na or NBu4), featuring a 9-phospha-10-boratriptycene
framework, was synthesized and characterized by NMR spectroscopy and
X-ray diffraction analysis. The NMR coupling constant of the corresponding
phosphine selenide indicated a higher electron-donating property of
the borate-phosphine L compared to that of the 9-phospha-10-silatriptycene
derivative (Ph-TRIP). The coordination property of L-X to [PdCl(η3-allyl)]2 was dependent on
the countercation, giving a neutral Pd complex [PdCl(η3-allyl)(L-NBu4)] from L-NBu4 in CH2Cl2 or a zwitterionic Pd complex [Pd(η3-allyl)(MeCN)(L)] from L-Na in MeCN/CH2Cl2. Utility of L-X as a ligand for metal catalysis was
demonstrated in the Pd-catalyzed Suzuki–Miyaura cross-coupling
of aryl chlorides.
