In the presence of ammonia, methyl N‐(bromoacetyl)anthranilate (4) is cyclized into 3H‐1,4‐benzodiaze‐pine‐2,5(1H,4H)‐dione (1). However, when 4 is replaced with methyl N‐(chloroacetyl)anthranilate (6), the only heterocyclic product formed in the reaction is 2‐(chloromethyl)quinazoline‐4(3H)‐one (7). Under analogous conditions, 3‐haloacetamidocrotonates (9, 10) do not yield any heterocyclic products and no 1,4‐diazepines can be obtained.

The electrodeposition of FePt alloy film in a novel ferric electrolyte that could be an alternative electrolyte to the usual non-stable baths was investigated. The influence of the applied current density and electrolyte temperature on the composition of the alloy was studied. It was found that co-deposition of oxygen can be reduced by deposition at higher temperature of 65 o C than room temperature. The as-deposited film had a face-centered cubic (γ-Fe,Pt) structure, and after an additional annealing process, the structure was changed to a face-centered tetragonal structure. The as-deposited FePt film also shows good resistance to corrosion and its coercivity was about 0.1T, which makes it suitable for use in applications compatible with silicon technology.

Because of pharmacological interest, title reactions are studied using the bromoacetyl derivative (I) which in the absence of Et3N yields only low amounts of (III) but 62% (IV).
