Click the structures and reaction arrows in sequence to view the 3D models and animations respectively A cyclic ketone can only exist as atrans-enolate. This enolate reacts with the aldehyde to give theantialdol product via a chair transition state with the aldehyde substituent equatorial. ...
Interactive 3D animations to predict stereochemistry of endo product of Diels-Alder reaction for students studying University courses
Increases in both chemical kinetics knowledge and the capacity of computers have led to the availability of very large detailed kinetic mechanisms for many problems. These mechanisms may contain up to several thousand species and several ten thousand rea
To gain further insight into the molecular packing, based on the x-ray structures, we then examine the layer-by-layer crystal structure of these compounds for possible interactions. According to Kasha’s exciton model37, the coupling of transition dipole moment plays an important role in determini...
