Participants

Reaction Steps

A solution of dimethyl 2-bromobenzylphosphonate (10.35 g) in dry DMF (50 ml) was added dropwise at room temperature to a stirred suspension of sodium hydride (0.979 g) in dry DMF (100 ml) (effervescence). After 20 minutes, a solution of furfural (3.56 g) in dry DMF (50 ml) was added (exotherm) and the resulting mixture was stirred at room temperature for 4 hours, then diluted with water and extracted with ether. The extracts were washed with water, treated with magnesium sulphate and charcoal, filtered, concentrated under reduced pressure, and chromatographed using 40°-60° C. petrol as eluant to give E-1-(2-furyl)-2-(2-bromophenyl)-ethylene (3.755 g), a pale yellow liquid (containing about 6% of the corresponding Z-isomer by GC).
