Marshall, Philip; Mooney, Brett; Prager, Rolf; Ward, A. David published the artcile< A convenient synthesis of (E)-Δ3,3'-biphthalides>, Related Products of 118-45-6, the main research area is biphthalide; phthalic anhydride condensation triphenylphthalidylphosphonium bromide.
Treating phosphonium salts I (R = R1 = H, MeO; X = halo) with phthalic anhydrides II (R2 = H, Cl, Me, MeO; R3 = H, MeO, NO2; R4 = H, MeO; R3R4 = OCH2O; Z = S O) in CH2Cl2 in the presence of Et3N gave 70-95% biphthalides III.
Synthesis published new progress about 118-45-6. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, Related Products of 118-45-6.
