Square-Planar Palladium Complexes with Trans Di- and Tribenzylphosphine Ligands Bearing O(CH2)4CH═CH2 Substituents; Two- and Three-Fold Intramolecular Ring-Closing Metatheses
摘要:
When trans-PdCl2{PPhn[CH2C6H4O(CH2)(4)CH= CH2](3-n)}(2), with ortho or meta C6H4 linkages and n = 0, 1 (tribenzyl- or dibenzylphenylphosplune cores), are treated with Grubbs' catalyst and then H-2/PtO2 the macrocycles trans-PdCl2{P[CH2-o-C6H4O(CH2)(10)O-o-C6H4CH2][CH2-o-C6H4O (CH2)(10)O-o-C6H4)CH2] P[CH2-o-C6H4O(CH2)(10)O-o-C6H4CH2]}, trans-PdCl2{PPh[CH2C6H4O(CH2)(10)OC6H4OCH2]}(2) (o- or m-C6H4), and trans- PdCl2{PPh[CH2-m-C6H4O(CH2)(10)O-m-C6H4CH2]}(2)Ph P} are isolated in high yields
