Fig. 4.7 exo-Insertion product of norbornene into catalyst 2
(naked palladium) (numbering system corresponds to
Fig. 4.8).
Fig. 4.8 1 H- 13 C 2D correlation spectrum of the reaction mixture of naked palla-
dium (marked * in the spectrum) and norbornene (marked n in the spectrum) and
model compounds (numbering system corresponds to Fig. 4.7).
By contrast, when a sample of catalyst 2 was dissolved in CDCl 3 and about 1
equiv of norbornene were added, the resulting reaction was so slow that the inser-
tion reaction could be followed by NMR spectroscopy. After addition of an equiva-
lent of norbornene, the 1 H NMR spectrum was taken within 30 min. Along with
