method for the synthesis of acylboranes, a rare class of organoboron compounds. Here a critical mechanistic insight into this new bora-Negishi methodology is offered by combining experimental and computational efforts. The studies demonstrate the monoligated nature of the Pd active species and guided the access to related Pd precursors with improved performance.
