Participants

Reaction Steps

A solution of 3-azido-2-thiophenecarbaldehyde (11-1, 1.00 g, 6.53 mmol, 1 equiv, prepared by the method of Gronowitz, S., Westerlund, C., and Hornfeldt, A.-B. Acta. Chem. Scand. B 1975, 29, 224-232) and triphenylphosphine (1.71 g, 6.53 mmol, 1.00 equiv) in THF (30 mL) was stirred at 23° C. for 6 h. The reaction mixture was concentrated to give 3-[(triphenylphosphoranylidene)amino]-2-thiophenecarbaldehyde (11-2). 1H NMR (400 MHz, CD3OD) δ 10.35 (s, 1H), 7.72 (m, 6H), 7.58 (m, 2H), 7.49 (m, 6H), 7.27 (dd, 1H, J=4.5, 0.8 Hz), 6.09 (d, 1H, J=4.5 Hz).
