a

Reaction conditions: 3 (0.134 mmol), 4 (0.16 mmol), K2CO3 (0.27 mmol), Pd(PPh3)4 (6.7 μmol), DME (1 mL), 110 °C, 24 h.

b

Isolated yields.

c

Numbers in parentheses indicate estimated (in reference to the starting material) yields according to 31P NMR.

d

For fractions that, after purification, were contaminated with up to 5–7% of Ph3P(O), the yields of products were calculated according to 1H NMR.

e

Reaction was carried out in a 1 mmol scale starting from 0.389 g of 3b, 4n (1.2 mmol), K2CO3 (2 mmol), Pd(PPh3)4 (0.05 mmol), DME (5 mL), 110 °C, 24 h.

f

8h was contaminated with 2% of 3d according to 1H NMR.
