Spectroscopic identification of interstellar relevant 2-iminoacetaldehyde

Abstract

Simple aldimines play a fundamental role in organic synthesis and some of them have been detected in space. Here we present the infrared and UV/Vis spectroscopic characterization of 2-iminoacetaldehyde using cryogenic matrix isolation techniques.

Synthesis and Characterization of N-Unsubstituted 2- and 3-Furanimines

“…17 Several functionalized aldimines, probably more reactive or with a high boiling point, were characterized among several compounds on a cold window by infrared spectroscopy. 18,19 On the other hand, N−H aldimines and ketimines bearing a furan moiety have never been synthesized. N-Substituted 2furanmethanimines are present in many drugs as antibiotics: cefuroxime, cefuroxime axetil, second generation oral cephalosporin antibiotics, 20 or also antimicrobials: 21 furazolidone, nitrofurazone, or antiprotozoal and antifungal agents: nifuratel, 22 for the treatment of American trypanosomiasis or Chagas disease, or a muscle relaxant: dantrolene.…”

“…The synthesis of arylaldimines, more difficult compounds to vaporize, was achieved by other approaches such as the reaction of azides with a ruthenium complex but without isolation of the product . Several functionalized aldimines, probably more reactive or with a high boiling point, were characterized among several compounds on a cold window by infrared spectroscopy. , …”
