(t-Bu)2]]2Pd(Br)(C10H7) (6). Method A: cis- and trans-6 was formed
by following a procedure similar to that of 4a using ligand 2e
(15.6 mg, 0.031 mmol), Pd2(dba)3 (14.0 mg, 0.015 mmol) and
1-bromonaphthalene (19.5 mg, 0.094 mmol).
Method B: cis- and trans-6 was formed by following a procedure
similar to that of 4a using complex 3 (27.1 mg, 0.032 mmol) and
1-bromonaphthalene (19.5 mg, 0.094 mmol).

Method C: Ligand 2e (15.6 mg, 0.031 mmol), Pd2(dba)3 (14.0 mg,
0.015 mmol), 1-bromonaphthalene (19.5 mg, 0.094 mmol) were
stirred together in THF (4 mL) for 3 h. The reaction mixture was
then filtered over a layer of celite and the filtrate was concentrated
to 0.5 mL. Hexane was layered over the THF solution and left upon
standing at ꢁ30 ꢂC for 24 h, giving brown precipitate of 6.

6. General procedure for coupling reactions of aryl halides
with organoboronic acids
A typical procedure is given for the reaction represented by
Entry 8 in Table 1. Ligand 2e (6 mg, 0.01 mmol), Pd2(dba)3
(5 mg, 0.005 mmol), 2-methylnaphthyl-1-boronic acid (223 mg,
1.2 mmol), Cs2CO3 (975 mg, 3 mmol) were introduced to a flask
under N2 gas. 1-bromo-2-methylnaphthalene (221 mg, 1 mmol)
was added into the flask, followed by addition of THF (5 ml) by
a syringe. The mixture was stirred under reflux for 24 h, under
ambient pressure of N2. The solvent was then removed under
reduced pressure. The resultant residual mixture was diluted with
H2O (10 ml) and Et2O (10 ml), followed by extraction twice with
Et2O. The organic extract was collected and stripped of solvent
under vacuum. The product was isolated by column chromatog-
raphy on silica eluting with hexane/ethyl acetate to give 276 mg
(98%) of 2,20-dimethyl-1-10-binaphthalene as a solid, which was
verified by GC/MS.
