Abstract Reaction of pyrrole-2,5-biscarbonitrile with 2-amino-2-methyl-1-propanol gave the bis{2-(4,4‘-dimethyl-4,5-dihydrooxazolyl)}pyrrole (dmoxpH) (1), which was deprotonated and reacted with [PdCl2(COD] to give [Pd2(dmoxp)2Cl2] (2) and [Pd3(dmoxp)2Cl4] (3). The former is an active catalyst in the Suzuki cross coupling of phenylboronic acid with activated and nonactivated aryl bromides at 70 °C and catalyst/substrate ratios of 10-4 to 10-5.
