 Abstract    M alco lm B id d l e st o n e a n d R o b e rt A. S h a w D epartm ent The title compound was synthesized and its structure determined by X -ra y crystallo­ graphy. The NPPI13 substituent adopts a type I conformation with its nitrogen and phosphorus atom s coplanar w ith the ring. The compound, the first asymm etric 1,3,5-triazine to be crystallographically investi­ gated, shows significant variations in ring bond lengths and angles; these are discussed.

 Title    Vinamidinium-Salze als Nucleophile Vinamidinium Salts as N ucleophiles  
 Abstract    1,4-diazepinium salts could not be aminomethylated with conventional methods, but the hydrochlorides produced with methyleniminium salts the C-Mannich-compounds. The reactivity of the substrate was mainly controlled by electronic effects of the substituents. Aminomethylation of 1,5-diazapentadienium salts occurred only if the conformations caused no steric hindrance of the ß-C-atom. Methyl substituted 2,3-dihydro-1,4-diazepinium salts reacted with 1,3,5 triazine to pyrimidine anellated derivatives.
