Some caution is necessary here as it has been reported that an intermolecular base-assisted deprotonation can take place (in the presence of bidentate phosphine ligands), see ref. 25b. For monodentate ligands, it was not possible to distinguish between inter- and intra-molecular base-assisted deprotonation reactions. Relevant references: D. García-Cuadrado A. A. C. Braga F.

During the submission of this paper, we ran two reactions of 5a→ 6a where THF was replaced by DMF under otherwise identical conditions to those given in entry 8, Table 1. In both cases, no product formation was observed

During the final preparative stages of this manuscript we found a report on a 'Heck-like' reaction of a coumarin containing a tethered aromatic bromide. Whilst the reaction requires a higher temperature (100 °C) and unique Pd precatalyst containing a 1,2-cyclobutadiene-substituted CpCoCb diphosphine ligand, it operates in dioxane solvent with DABCO as the base, see: C.-P. Chang S. V. Pradiuldi F.-E. Hong Inorg. Chem. Commun. 2009 12 596 598 No further mechanistic details were provided in this paper (vis-à-vis CMD (AMLA-6) versus Heck-like reaction pathways).
