1,2,4,5-Tetra((3-(2,2¢-bipyridin-5-yl)ethynyl)bicyclo-
[1.1.1]pent-1-ylethynyl)benzene (7).A 25 mL two-neck
flask was charged with 20 (309 mg,1.14 mmol) and 1,2,4,5-
tetraiodobenzene (158 mg,0.272 mmol),evacuated,and filled
with argon.Dry piperidine (10 mL) was added from a syringe,
and the solution was degassed by three freeze-pump-thaw
cycles.Then,Pd(PPh3)4 (33 mg,2.5 mol %) was added from a
tip tube,and the reaction mixture was stirred for 6 days at 50
°C.Additional Pd(PPh3)4 (18 mg,1.25 mol %) was added from
a tip tube,and the reaction was continued for 5 more days.
Then,NaOH (4 M in water,5 mL) was added,and the mixture
was stirred for 10 min.The solvents were removed under
reduced pressure,and chloroform was added.The organic layer
was washed with EDTA (1 M,3 \2 10 mL),dried over Na2SO4,
and evaporated under reduced pressure.The crude product
mixture was separated by HPLC (C18,acetonitrile/chloroform-
2.5% Et3N),and 7 was obtained as an off-white solid:174 mg
