摘要

Studying the influence of the amine basicity, we found that amines having higher basicity than the aromatic ones, for the preparation of amides of type 5, gave, in addition, the phosphorotriamides 7 as a by-product. These compounds were prepared by reacting 1 with amines 2 in the presence of a tertiary base (Scheme B. Table 1). It was also demonstrated that such phosphorotriamides do not react with carboxylic acid salts to form the ...
