The paper considers Bergman type operators introduced by Shields and Williams depending on a normal pair of weight functions. We prove that there exist values of parameter s for which these operators are bounded on mixed norm spaces L(p, q, s) on the

Banach spaces $h_\infty (\varPhi)$, $h_0 (\varPhi)$ and $h^1(\eta) $ of functions, pluriharmonic in the unit ball in $\mathbb{C}^n$, depending on weight function $\varPhi$ and weighting measure $\eta$ are introduced. The question we consider is: for

A number of aldimines of 7-aminopyrrolo[2,3-d]pyrimidine have been synthesized by the action of bromine on hydrazones of 5-allyl-4-hydrazinopyridine. The structures of the compounds obtained were confirmed by IR spectroscopy and mass spectrometry.

The action of bromine on 5-allyl-6-aminopyrimidines was studied. The formation of both a product of addition of bromine to the allylic bond and pyrrolo [2,3-d]-pyrimidines is possible, depending on the character of the substituent attached to the ami

A new scheme was developed for the synthesis of 2,4-dimethy1-5,6-dihydro-6-bromomethylthieno[2,3-d]pyrimidine by bromination of the corresponding 5-allyl-6-mercaptopyrimidine. It is shown that when the bromomethyl derivative is treated with sodium me
