Publikováno v: Journal of Mathematical Sciences. 161:375-383

A cover of a manifold X is called an r-cover if any r points of X belong to a set in the cover. Let X and Y be two smooth manifolds, let Emb(X, Y) be the family of smooth embeddings X → Y, let M be an Abelian group, and let F: Emb(X, Y) → M be a

Synthesis and reactions of mixed halogenobuta-1,3-dienes

Autor: V. A. Zapol'skii, R. V. Kaberdin, Vladimir I. Potkin

Publikováno v: Russian Chemical Reviews. 68:765-779

The published data on the methods for the preparation of mixed halogenobuta-1,3-dienes are generalised and systematised with a special emphasis on compounds of high practical value. Chemical transformations of mixed halogenodienes are considered and

Nitrobutadienes and their halogen derivatives: synthesis and reactions

Autor: R. V. Kaberdin, V. A. Zapol'skii, Vladimir I. Potkin

Publikováno v: Russian Chemical Reviews. 66:827-842

The main methods of the synthesis of nitrobutadienes and their halogen derivatives, which are multipurpose electrophiles, are surveyed. The literature data on their chemical transformations are generalised, the possibilities for the preparation of ne
