The present work describes convenient synthesis of the novel Schiff bases 4, 5 and 6 by reaction each previously synthesized quinazolinones 1, 2 3 with p-methoxybenzaldehyde. [2+2] Cycloaddition Reaction former within phenylisothiocyanate affording azatedine derivatives 7 8. Also, quinazolines 1 could be reacted α-bromoglucose tetraacetate giving peracetylated N-glycosides 9 10 which were then ...

In the title compound, C(14)H(10)Cl(2)INO(3)S, the dihedral angle between the benzene rings is 52.13 (10)°. In the crystal, the components are linked by pairs of N-H⋯O(sulfon-yl) hydrogen bonds into centrosymmetric dimers.

This research evaluates the efficiency of nanosized ZnO in the catalytic ozonation of 4-chloro-2-nitrophenol and determines the effect of pH on heterogeneous catalytic ozonation. The combined use of ozone and ZnO catalyst leads to conversion of 98% 4-chloro-2-nitrophenol during 5 min. In addition, it was found that in ZnO catalytic ozonation, the degradation efficiency of 4-chloro-2-nitrophenol...

The mechanisms of the gas-phase elimination kinetics of 1-chloro-3-methylbut-2-ene and 3-chloro-3-methylbut-1ene and their interconversion have been examined at MP2 and DFT levels of theory. These halide substrates yield isoprene and hydrogen chloride. The results MPW1PW91 calculations agree with the experimental kinetic parameters showing the elimination reaction occurs at greater rate for 1-c...
