Kinetic and computational evidence for an intermediate in the hydrolysis of sulfonate esters.

Org. Biomol. Chem. 10(40) , 8095-101, (2012)

The hydrolytic reactions of sulfonate esters have previously been considered to occur by concerted mechanisms. We now report the observation of a break in a Brønsted correlation for the alkaline hydro...

CE-ESI-MS analysis of singly charged inorganic and organic anions using a dicationic reagent as a complexing agent.

Electrophoresis 30(22) , 3918-25, (2009)

A dicationic ion-pairing reagent, N,N'-dibutyl 1,1'-pentylenedipyrrolidinium, was used to form complexes with singly charged anions for their subsequent analysis by CE-ESI-MS in positive ion mode. Thi...

Synthesis, structure and in vitro antibacterial activities of new hybrid disinfectants quaternary ammonium compounds: pyridinium and quinolinium stilbene benzenesulfonates.

Eur. J. Med. Chem. 45 , 4199-208, (2010)

The series of pyridinium (1-10) and quinolinium (11-20) stilbene benzenesulfonates have been synthesized and their structures were investigated by UV-vis, FT-IR and (1)H NMR spectroscopy. In addition,...
