abstract

  • When trans-PdCl2{PPhn[CH2C 6H4O(CH2)4CH=CH2] 3-n}2, with ortho or meta C6H4 linkages and n = 0, 1 (tribenzyl-or dibenzylphenylphosphine cores), are treated with Grubbs catalyst and then H2/PtO2, the macrocycles trans-PdCl2{P[CH2-o-C6H4O(CH 2)10O-o-C6H4CH2][CH 2-o-C6H4O(CH2)10O-o- C6H4)CH2]P[CH2-o-C6H 4O(CH2)10O-o-C6H4CH 2]}, trans-PdCl2{PPh[CH2C6H 4O(CH2)10OC6H4CH 2]}2 (o-or m-C6H4), and trans-PdCl2{PPh[CH2-m-C6H4O(CH 2)10O-m-C6H4CH2] 2PhP} are isolated in high yields. 2010 American Chemical Society.
