H. Trabelsi et al., APPLICATION OF THE STAUDINGER REACTION TO SYNTHESIS OF 2-F-ALKYLATED ETHYL CARBODIIMIDES AND F-ALKYLATED HETEROCUMULENES, Phosphorus, sulfur and silicon and the related elements, 90(1-4), 1994, pp. 185-191
The reaction between 2-F-alkylethyliminophosphoranes and carbon disulf
ide or carbon dioxide affords carbodiimides and heterocumulenes. The s
elective formation of one of these depends on the nature of the solven
t and on the stoichiometric conditions.
