WitrynaReductive amination with zinc powder in aqueous media. Reductive amination is the name usually employed to indicate a synthetic protocol for the preparation of amines that involves a two-step reaction between a carbonyl compound and a primary or secondary amine (or even ammonia or ammonium salts), in the presence of a selective … In organic chemistry, an imine is a functional group or organic compound containing a carbon–nitrogen double bond (C=N). The nitrogen atom can be attached to a hydrogen or an organic group (R). The carbon atom has two additional single bonds. Imines are common in synthetic and naturally occurring compounds and they participate in many reactions.

Witryna14 kwi 2024 · When the logarithm of the decimal reduction time, D, is plotted against temperature, a straight line results. This plot is called the thermal death time (TDT) curve (Figure 6.2.3). From such a plot, the thermal sensitivity of a microorganism, z , can be determined as the temperature change necessary to vary TDT by one log cycle. WitrynaThe imino Diels-Alder (IDA) reaction may occur either by a concerted or stepwise process. The lowest-energy transition state for the concerted process places the imine lone pair (or coordinated Lewis acid) in an exo position. Thus, ( E) imines, in which the lone pair and larger imine carbon substituent are cis, tend to give exo products.
