Abstract

Thermal decomposition of the palladium (aryl) neopentoxide complexes [PP] Pd (Ar) OCH2CMe3 [PP= Tol-BINAP or BINAP; Ar= p-C6H4CHO (1b), p-C6H4COPh (1c), p- C6H4NO2 (1d), o-C6H4NO2 (1e), o-C6H4CN (1f)] possessing substituents on the palladium- bound aryl group suitable for delocalization of negative charge led to quantitative (≥ 95%) formation of aryl ether without detectable β-hydride elimination. Thermal decomposition of ...
