fabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
Regio- and stereoselective synthesis of new diaminocyclopentanols
The optimal conditions for regio- and stereoselective epoxide ring opening of N,N-disubstituted 1,2-epoxy-3-aminocyclopentanes by different nucleophilic reagents have been developed. The substituents on the nitrogen atom in the epoxide precursor and the orientation of the oxirane ring are crucial for the reaction outcome. Thus, treatment of (1RS,2SR,3SR)-1,2-epoxy-3-(N,N-dibenzylamino)cyclopent...
متن کاملRegio- and Stereoselective Oxysulfonylation of Allenes.
A highly regio- and stereoselective oxysulfonylation of allenes was developed that provided direct access to 2-sulfonyl allylic alcohols in good yields. By means of dioxygen activation, selective difunctionlization of allenes could be successfully achieved under mild metal-free conditions. Preliminary mechanistic investigation disclosed that this transformation probably goes through a radical p...
متن کاملRegio- and stereoselective aminopentadienylation of carbonyl compounds.
A simple and robust protocol is detailed for the preparation of enantioenriched α-substituted (1,4-pentadien-3-yl)amine derivatives. The methodology involves the addition of an in situ formed pentadienyl indium reagent to chiral tert-butylsulfinimines, previously formed in the same pot. The addition takes place with excellent γ-regio- and diastereoselectivity for a wide range of carbonyl compou...
