Abstract
A sterically protected diphosphinidenecyclobutene/palladium system has been used to mediate the catalytic cross-coupling of aryl bromides with organostannanes. An air- and moisture-stable diphosphinidenecyclobutene ligand proved the efficiency and generality of this class of ligand for cross-coupling reactions.
Key words
Stille cross-coupling - diphosphinidenecyclobutene - palladium - aryl bromides
