Ma. Aramendia et al., Electrospray ionization mass spectrometry detection of intermediates in the palladium-catalyzed oxidative self-coupling of areneboronic acids, J ORG CHEM, 64(10), 1999, pp. 3592-3594
Several intermediates of the oxidative coupling of areneboronic acids to af
ford biaryls have been identified by electrospray ionization mass spectrome
try. Knowledge has been gained about the steps occurring after the biaryl f
ormation and leading to the recovery of the catalytic species.
