Abstract
The bicyclic sulfur-nitrogen heterocycle F3CCN5S3 (1) was investigated as a donor and acceptor toward H+, metal cations, and F−. Whereas the protonated species F3CCN5S3H+ AsF6 − (2) can be isolated, the product of the reaction with F− is unstable and decomposes among other products to TAS+ F3CCN5S3NC(NH2)CF3 − (3), which is isolated from this reaction in small amounts.
