The scope of 1,3,5-triazine inverse electron-demand Diels-Alder (IDA) reactions was expanded to include aminothiophenecarboxylic acids as latent dienophiles. A series of 2-amino-3-thiophenecarboxylic acids (1a-d) and a 3-amino-2-thiophenecarboxylic acid (5) were introduced as productive dienophiles
## An extraction-spectrophotometric method is described for the determination of traces of zinc with 2-t 2-( 3,5-dibromopyridyl)azo] -5-dimethylaminobenzoic acid. The reagent forms a stable, blue 1:2 zinc/reagent complex that can be extracted into chloroform. The apparent molar absorptivity of the
