Cyclic Oligophosphonic Anhydrides Stable in Aqueous Media
Depending on reaction conditions, the phosphonylation of N-alkylacetamides with H3PO3-P C I3 in B-HC1 media (B = Py, Bu3N) gives either l-alkylaminoethylidene-l,l-bisphosphonic acids (la—e) or previously unknown l-alkylaminobutane-l,l,3,3-tetrayl-tetrakisphosphonic dianhydrides (2a-e). The latter convert into monocyclic forms (3a-e) under mild acidic hydrolysis. Acyclic forms (4a-e) cannot be i...
متن کاملInternal strain on the bond length and rate of hydrolysis in cyclic amides
The internal strain in cyclic amides are explained as a factor of resonance that are effected on the bond length C-N and are a major factor of rates of hydrolysis. The cyclic amides in this study are optimized by Gaussian program and the bond length of C-N in the rings are studied by HF/6-31G*.
