The Reaction of Wittig and Wittig-Horner Reagents and Alkyl Phosphites with 1,2-Naphthoquinone-1-benzimide. -In order to determine the preferential site of attack of organophosphorus reagents towards quinone imines, the action of phosphonium ylides (II), the anions of phosphonoacetates (V), and alk
Wittig-Horner reagents (1a-e) react with 1,3-dioxo-D 2,␣ -indanmalononitrile (2) to give the phosphonate adducts 3, 4, 5, 6, and 7, respectively. Structural reasoning for the new products was based on compatible analytical and spectral data (IR, 1 H, 31 P NMR, and MS). The mechanism that accounts fo
Wittig reagents 1a,b react with dicyanomethylene derivatives of fluorenone (3) and xanthone (4) to give the corresponding phosphoranylidenecyclobutylidene adducts 6a, 6b, 9a, and 9b. On the other hand, the reaction of Wittig-Horner reagents (2) with the same nitriles 3 and 4 afforded the respective
