CHEMISTRY OF PHOSPHOROUS YLIDES 10 REACTION WITH PHOSPHACUMULENES IV. SYNTHESIS OF PYRAN, PHOSPHORANYLIDENE, OXAPHOSPHORIN AND OXAZAPHOSPHORIN FROM THE REACTION OF 1,3-DIOXO-Δ2,α-INDANEMALONONITRILE WITH PHOSPHORANES AND IMINOPHOSPHORANES

1,3-Dioxo-Δ2,α-indanmalononitrile (1) reacts with the active ketenylidene-(2a) and thioketenylidenetriphenyl phosphorane (2b) to give the corresponding pyrans 3 (X=O or S).The reaction of pyran 3 with p-nitroaldehyde proceeds according to the W
