palladium(II) chloride (1.7 mg, 0.01 mmol), 9Ј (18.8 mg,
0.02 mmol) and a base (2.0 mmol) were placed in a 20 mL Schlenk
flask. The flask was evacuated and back-filled with nitrogen before
adding DMF (1.0 mL), the aryl bromide (1.0 mmol) and styrene
(0.114 mL, 1.0 mmol). The solution was stirred at the designated
temperature and time. Subsequently the mixture was filtered and
concentrated in vacuo. The crude material was purified by CTLC
on silica gel. A similar procedure was applied in the case of catalyst
precursor 11 (19.91 mg, 0.01 mmol).

X-ray Crystallographic Studies: Suitable crystals of 5_O, 8 and 11
were sealed in thin-walled glass capillaries under nitrogen and
mounted on a Bruker AXS SMART 1000 diffractometer. Intensity
data were collected in 1350 frames with increasing ω (width of 0.3°
per frame). The space groups were determined on the basis of the
Laue symmetries and systematic absences, and confirmed by using
structure solution methods. The structures were solved by direct
methods using the SHELXTL package.[22] All non-hydrogen atoms
were located from successive Fourier maps and hydrogen atoms
were refined by using the riding model. Anisotropic thermal pa-
rameters were used for all non-hydrogen atoms and fixed isotropic
parameters were used for hydrogen atoms. The crystallographic
data for 5_O, 8 and 11 are summarized in Table 2.
