Abstract
The reaction of 2,2'-ethylidenebis(4,6-di-tert-butylphenol)(EDBP-H(2)) with sodium, Al(Me)(3) and BnOH with a molar of ratio of 1:1:1:1 in THF gives hetero-bimetallic complex of [(EDBP)Al(CH(3))(mu(2)-OBn)Na(THF)(3)](1) in 85% yield. In order to investigate the different anion effects on the ROP of epsilon-caprolactone, complexes [(EDBP)(2)Al][(Li)(THF)(2)] (2) and [(EDBP)(2)Al][(Na)(THF)(2)] (3) were prepared in an analogous manner to that of 1 in 63% and 71% yields respectively. Experimental results show that hetero-bimetallic complex 1 is an efficient catalyst for the ring-opening polymerization of epsilon-caprolactone. (C) 2011 Elsevier B.V. All rights reserved.
