Synthesis of 1-phosphono-2-aza-1,3-dienes and their conversion into 1- vinyl-2-phosphonoaziridines
Stevens, Christian,Gallant, Marc,De Kimpe, Norbert
, p. 3457 - 3460 (1999)
1-Phosphono-2-aza-1,3-dienes were formed by 1,4-dehydrochlorination of the corresponding N-(phosphonomethyl)-a-chloroimines, and reacted smoothly with diazomethane to give 1-vinyl-2-phosphonoaziridines.
