Abstract
Treatment of the N[2-(OH)C6H4], a, and 2,3,4-(MeO)3C6H2C(H)N[2-(OH)-4-MeC6H4], b, with N[2-(O)C6H4]}]n, 1a, and [Pd{2,3,4-(MeO)3C6HC(H)N[2-(O)-4-MeC6H4]}]n, 1b, respectively, as air stable solids,
with the [C,N,O] N[2-(O)C6H4]}(PPh3)], 2a, and [Pd{2,3,4-(MeO)3C6HC(H)N[2-(O)-4-MeC6H4]}(PPh3)], 2b, with cleavage of the polynuclear structure. The molecular structure of 2a has been determined by N[2-(O)C6H4]})2{μ-PPh2(CH2)nPPh2}]
(3a: n = 1; 4a: n = 3; 5a: n = 4; 6a: n = 5), [(Pd{2,3,4-(MeO)3C6HC(H)N[2-(O)C6H4]})2(μ-PPh2C5H4FeC5H4PPh2)], 7a, [(Pd{2,3,4-(MeO)3C6HC(H)N[2-(O)-4-MeC6H4]})2{μ-PPh2(CH2)nPPh2}]
(3b: n = 3; 4b: n = 4) and [(Pd{2,3,4-(MeO)3C6HC(H)N[2-(O)-4-MeC6H4]})2(μ-PPh2C5H4FeC5H4PPh2)], 5b, as air stable solids. Treatment of 1a and 1b with an excess of mono- or diphosphine did not produce cleavage of the Pd–Ochelating bond.
