Stable hemiaminals with a cyano group and a triazole ring.
Under neutral conditions the reactions between 4-amino-1,2,4-triazole and cyano-substituted benzaldehyde derivatives yield stable hemiaminals. Addition of small amounts of acid catalyst promotes further step of dehydration resulting in formation of Schiff bases. Four new hemiaminals and the corresponding imines have been obtained. The molecular stability of the hemiaminal intermediates results ...
متن کاملNO donors: Focus on furoxan derivatives*
The article focuses attention on furoxan derivatives (1,2,5-oxadiazole 2-oxides) as NO donors. Possible mechanisms for NO release from these products in physiological solution and in segments of rabbit femoral artery are briefly considered. The in vitro antiaggregatory activities and the in vitro and in vivo vasodilating properties of a number of furoxans are examined with particular reference ...
متن کاملAn Introduction to Focus Group Research
A focus group refers to a group of people who share some common characteristics. A researcher gathers these people in the group in order that they share their points of view and interact with each other over a specific issue. Focus group and Interview group are used interchangeably in the scientific literature and both refer to a method of collecting data in qualitative studies. Given the impor...
متن کاملAn acid catalyzed reversible ring-opening/ring-closure reaction involving a cyano-rhodamine spirolactam.
Cyanamide was introduced into the rhodamine spirolactam framework to produce a colorless and non-fluorescent compound RBCN. It shows a reversible ring-opening/ring-closure process in response to the solution pH, which exhibits an "ON/OFF" switching in its fluorescence. Different from other rhodamine-type dyes, the ring-open form of RBCN is stable in protic solvents under neutral, near neutral a...
