Pd(II)-Catalyzed Decarboxylative Cross-Coupling of Oxamic Acids with Potassi-um Phenyltrifluoroborates under Mild Conditions. — The decarboxylative cross-coupling of oxalate (II) with (phenyl)trifluoroborate (I) leads to methyl benzoate (III). The analogous reaction of oxamic acids (IV) and (VI) with (aryl)trifluoroborates gives rise to corresponding N-mono- and N,N-disubstituted benzamides. — (LI, M.; WANG, C.; FANG, P.; GE*, H.; Chem.
