Ortho-palladation of (Z)-2-Aryl-4-Arylidene-5(4H)-oxazolones. structure and functionalization

Ortho-palladated complexes of (Z)-2-aryl-4-arylidene-5(4H)-oxazolones have been prepared through oxidative addition. The reaction of (Z)-2-phenyl-4-(2- bromobenzylidene)-5(4H)-oxazolone (4) with Pd2(dba)3 · CHCl3 gives the six-membered cyclopalladated dinuclear complex [Pd(μ-Br)(o-C6H4CH=CNC(O)OCPh)]2 (7). The reaction of 7 with PPh3 gives dinuclear 9, which incorporates one phosphine per Pd atom through cleavage of the Pd-N bond, and preserves the bromide bridging system. However, reaction with PPh2Me gives mononuclear 8, which incorporates two phosphines as a results of the cleavage of the μ-Br system and N displacement. In contrast, the reaction of 7 with pyridine gives complex 12 due to simple cleavage of the Br bridge, leaving the N-bonding intact. Therefore, three different reaction pathways have been characterized. The reactivity of the Pd-C bond in 7 has also been examined, and functionalized oxazolones can be obtained. The reaction of 7 with PhI(OAc)2 in acetic acid gives the starting oxazolone C 6H4-2-Br-CH=CNC(O)OCPh (4), through the presumed oxidation of the Pd center and C-Br bond formation by reductive coupling. In contrast, the reaction of the acetate dlmer 14 with PhI(OAc)2 in acetic acid gives C 6H4-2-OAcCH=CNC(O)OCPh (20) through C-O coupling. When treatment of 7 with PhI(OAc)2 is performed in MeOH or EtOH, the oxazolones C6H4-2-OR-CH=CNC(O)OCPh (R = Me (18), Et (19)) are obtained. The reaction of 7 with CO in alcohols ROH gives cleanly the oxazolones C6H4-2-CO2RCH=CNC(O)OCPh (R = Me (21), iPr (22)) through CO migratory insertion into the Pd-C bond and further nucleophilic attack of the RO-fragment.
