Unsuccessful synthesis of individual 1,1-dinitroethene

Abstract

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.
