Application

Nitrosyl tetrafluoroborate is an efficient nitrosating and diazotizing agent. It reacts with alcohols and secondary amines to yield alkyl nitrites and nitrosamines, respectively. It reacts with primary amines to yield diazonium tetrafluoroborates. NOBF4 is also a mild oxidant and commonly used for single electron transfer oxidation.

S-Nitrosylation of protein thiol groups by nitric oxide (NO) is a widely recognized protein modification. In this study we show that nitrosonium tetrafluoroborate (BF4NO), a NO+ donor, modified the thiol groups of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) by S-nitrosylation and caused enzyme
