Abstract

Dans le cadre de notre étude sur la réactivité spéifique des cations phosphéniums (R2P+: X, X=AlCl4, CF3SO3) nous montrons que les cations (1 à 4) reagissent sur les 1.3-diazadiènes a et b pour conduire, par une réaction de cycloaddition [1+4] auxdiazaphospholkniums (1a, 1b, 2a, 2b, 3a et 4b). La structure aux RX de la est présentee et cornmentée en comparaison à celle d'autres mono et dications organ-ophosphorés analogues.

In our study on the specific reactivity of phosphenium cations (R2P+: X. X=AlCl4, CF3SO3) we show that phosphenium cations (1 to 4) react easily with 1–3 diaza 1–3 dienes a and b leading to a [1 +4] cycloaddition to the corresponding diazaphospholenium cations (1a, 1b, 2a, 2b, 3a and 4b). The X-ray structure of la is described with comments and compared with other analogous phosphorus mono and dications.
