Abstract:
A new route to a pentaerythritol-based tetraamine is delineated and subsequently contrasted to a previous report. Access to the pure tetraamine is facilitated by the smooth reduction of its tetraazide precusor. Characterization includes the preparation of a 4:1 Zn-tetraphenylporphyrin/tetraamine complex.
