Yield:866611-28-1 87%

Reaction Conditions:

with sodium carbonate;tetrakis(triphenylphosphine) palladium(0) in 1,2-dimethoxyethane;water; for 5 h;Heating / reflux;Suzuki Coupling;

Steps:

3

9-Anthraceneboronic acid 10.7 g, 2-(4-bromophenyl)naphthalene 11.3 g and tetrakis(triphenylphosphine)palladium 2.3 g were mixed and substituted with argon. DME (dimethoxyethane) 140 ml and a 2M sodium carbonate aqueous solution 60 ml were added thereto, and the mixture was heated and refluxed for 5 hours. After left cooling, the deposited crystal was filtered and washed with ethanol and toluene. The crystal thus obtained was recrystallized from toluene, filtered and dried, whereby targeted (9-(4-naphthalene-2-yl-phenyl)anthracene 13.25 g was obtained (yield: 87 %).
