White phosphorus readily reacts with 2-chloro-5-(chloromethyl)thiophene under phase-transfer conditions (KOH, water, dioxane, benzyltriethylammonium chloride, 50-52 degreesC, 3 h) to form tris[(5-chloro-2-thienyl)methyl]phosphine oxide in good yield. This new phosphine oxide undergoes the Wittig - Horner reaction with benzaldehyde (NaNH2/THF system) leading to 2-chloro-5-[(E)-2-phenylethenyl]thiophene and bis[(5-chloro-2-thienyl)methyl]phosphinic acid.<
