The relative importance of three different routes for the N-nitrosation of amino acids (nitrosation by N 2 O 3 , by and by intramolecular migration of the nitroso group from the initially nitrosated carboxylate group) was investigated for methylaminobutyric acid, methylaminoisobutyric acid, azetidin

✦ Synopsis
The diazotization of N-silylated N-methyl-and N-phenylcyclopentenylamines affords products derived from intermediate methyl-and phenyldiazonium ions. However, when this method is applied to N,N-bissilylated cyclopentenylamines, the products obtained do not confirm the formation of a cyclopentenyl cation intermediate.

The rate constants were determined for the nitrosation reactions of the following substrates: Methyl (MU), Ethyl (EU),Propyl (PU)Butyl (BU), and Allylurea (AU). The rate equation found at a constant pH was: [Urea]. The reactions were carried out in pre-v ϭ k[HNO ] 2 dominantly organic media(dioxane
The kinetics of the nitrosation of methyl, ethyl. propyl. butyl, and ally1 urea were studied by conventional and stopped-flow spectrophotometry in the presence or absence of acetate or mono-di-, or trichloroacetate anions In the presence of a large excess of urea, the observed rate equation was whe
This article describes the synthesis and characterization of copolymers of methyl methacrylate (MMA) and N-4-chlorophenyl maleimide (PC)/N-3-chlorophenyl maleimide (MC). The copolymers were synthesized by varying the mole fraction of N-aryl maleimides from 0.1 to 0.5 in the initial feed using azobis
