CH3 NH Coniine Conine, C,H,„N, is the toxic principle of the poison hemlock drunk by Socrates. It can be synthesized from acrylonitrile (H,C=CHCN) and ethyl 3-oxohexanoste. The synthesis pro follows: 1. Deprotonation of ethyl 3-0xohexanoate to form enolate anion 1; 2. Michael addition to acrylonitrile to form intermediate 2: 3. Protonation to form Michael adduct 3; 4. Ester hydrolysis and decarboxylation to form oxonitrile 4; 5. Reduction to form oxoamine 5: 6. Cyclization to form imine 6. 1. Catalytic hydrogenation to form Coniine. Draw the structures of enolate anion 1 and imine 6.
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
