9--13

The possibility of the preparation of free 1,1-dinitroethene was examined experimentally on the basis of procedures described earlier for other examples of 1-R-1-nitroethenes. It was found, that these types of protocols are non-usable for the preparation of the title compound due to its high reactivity and tendency to decomposition and oligomerization.

Sterical index: a novel, simple tool for the interpretation of organic reaction mechanisms

A new, simple index for the quantitative description of steric effects was proposed based on the results of DFT calculations. This effect was connected with the disturbance of synchronicity within transition states of the model Diels-Alder reaction. The obtained results offer the possibility of predicting steric effects determined by alkyl groups for a wide range of bimolecular processes.
