M. Soleilhavoup et al., PHOSPHANYLCARBENES - FROM UNSTABLE INTERMEDIATES TO X-RAY CHARACTERIZED COMPOUNDS, Phosphorus, sulfur and silicon and the related elements, 76(1-4), 1993, pp. 309-312
The synthesis of original (phosphanyl)diazo derivatives possessing eit
her stannyl or phosphonio groups at the diazo carbon is described. The
reactivity of transient (phosphanyl)(stannyl)carbenes as well as prel
iminary X-ray data concerning a (phosphanyl)(phosphonio)carbene are pr
esented.
