Reaktionen von 2H-isoindolen mit aktivierten azo-verbindungen

The chemical behaviour of alkyl substituted 2H-isoindoles towards dialkyl-azodicarboxylates has been investigated and the structure of the resulting 1:1- and 1:2-adducts elucidated. The reaction of the o-quinonoid hetarenes with the activated dienophiles can be considered as a Michael addition.

Fast gel-permeation chromatography. I. A study of operational parameters

A systematic study of factors affecting the GPC separation showed that peak spreading with increasing flow rate was much less than predicted from the Van Deemter equation. Viscous fingering decreased and peak symmetry improved at increased flow rates. As a result, fast GPC analysis was shown to be readily attainable through optimization of operating parameters.     

Isoperimetrische Ungleichungen für elastisch gebundene Membranen auf Dreiseiten und auf Vierseiten

Summary Some isoperimetric inequalities for vibrating membranes are extended to an elastically supported boundary, using conformal transplantation. A further inequality for fixed-free boundaries is given in section 3.
