Autor: Nikolay S. Zefirov, A. I. Yurtanov, S. K. Baidildaeva, A. N. Chekhlov
Publikováno v: Russian Chemical Bulletin. 43:816-820
Ethyl α-halo-α-nitropropionate and -butyrate were prepared by alkylating ammonium salts of ethyl bromo- and chloronitroacetates. The addition of alkyl acrylates to alkyl chloronitroacetates or their salts gives dialkyl α-chloro-α-nitroglutarates.

Decomposition products of halonitroacetic acid derivatives
Autor: A. I. Yurtanov
Publikováno v: Bulletin of the Russian Academy of Sciences Division of Chemical Science. 41:120-122
The halonitro group O2NCHX of chloro- and bromonitroacetic acid derivatives underwent reduction to H2NCO upon boiling. The same derivatives decomposed to oxalic acid upon long storage. Likely chemical transformation pathways are discussed.
