説明

Reactions of tris (dialkylamino) phosphines P (NR2)3 with thiophthalic anhydride (TPA) or phthalic anhydride (PA) were investigated. PA reacted smoothly with P (NR2)3 to yield the corresponding acid amides in 90% over yield.<BR>TPA also reacted with P(NR2)3 to give a dimer of TPA and the corresponding acid amides. The dimer of TPA consisted of two components (3), (4) and the ratio of (3) to (4) was 1:9. The ratio did not vary with the solvents and reaction conditions. PA is dimerized by trialkylphosphite P (OR)3, but a dimer of PA was not detected in the reaction with P (NR2)3.
