Unusual Interaction of Ag+ with an Organopalladium Crown Ether. Synthesis and Structures of [PdCl(L)] and [Pd(H2O)(L)(Ag)][CF3SO3]2 (L = 5,8,11-Trioxa-2,14-dithia-[15]-m-cyclophane)
摘要:
Reaction of 2 equiv of [Ag][CF3SO3] with the organopalladium crown ether [PdCl(L)] (L = 5,8,11-trioxa-2,14-dithia[l5]-m-cyclophane) results in formation of AgCl and encapsulation of the second Ag+ ion to form the bimetallic complex [Pd(H2O)(L)(Ag)][CF3SO3](2). The X-ray structure of [Pd(H2O)(L)(Ag)][CF3SO3]2 . CH2Cl2 shows that the electrophilic Ag+ ion is bound to the Pd-C(aryl) unit and that this interaction is complemented by peripheral coordination to the ether oxygens and a counterion.
