摘要：

Ethynyl substituted bipyridine chelates react with bromo or triflate functionalized bipyridine or terpyridine subunits, in the presence of catalytic amounts of Pd0(PPh3)4 to yield, the new homo- and heteroditopic ethynyl bridge ligands 2a, 4a, 7a and 8. Self coupling of the ethynyl substituted bipyridine species in the presence of CuCl/TMEDA/O2, yield the symmetric diethynyl bridge ligands 2b, 4b and 7b.
