This paper reports on the firstexample of pH-dependent cross-coupling reactions of water-soluble organic halides (3-X(C6H4)CO2H, where X = Cl, Br, I) with organoboron compounds (PhB(OH)2 and Ph4BNa) to form 3-Ph(C6H4)CO2H, catalyzed by the mononuclear organometallic aqua complex [(SCS)PdII(H2O)]2(SO4) ([1]2(SO4), SCS = C6H3-2,6-(CH2SBut)2) in basic media (8 < pH < 13, NaHCO3/NaOH buffers). The structure
