We overview the results on topic of compound Poisson approximation to distribution a sum Sn=X1+⋯+Xn (possibly dependent) random variables. indicate number open problems and discuss directions further research.

Reaction between 5-methyl-3-aminoisoxazole and ?-acetamidophenylsulpho-nylchloride yielded compound 1. Hydrolysis of compound 1 gave a starting compound 4-methoxybenzal-?-5-methyl isoxazol-3-yl-sulphonamido aniline 2. The compound 2 on condensation with different aldehydes and potassium cyanide yielded the nitriles 3a-l. Cyclocondensation between oxazolinone and compound 2 yielded imidazolines ...
