WebSep 20, 2013 · Organofluorophosphonium salts of the formula [ (C 6 F 5) 3–x Ph x PF] [B (C 6 F 5) 4] ( x = 0 or 1; Ph, phenyl) are shown to form adducts with neutral Lewis bases and to react rapidly with fluoroalkanes to produce difluorophosphoranes. WebThe phosphonium structure is converted to phosphine oxide as the result of this reaction. [5] [P (CH 2 OH) 4 ]Cl + NH 2 CONH 2 → (HOCH 2) 2 POCH 2 NHCONH 2 + HCl + HCHO + H 2 + H 2 O This reaction proceeds rapidly, forming insoluble high molecular weight polymers. The resulting product is applied to the fabrics in a "pad-dry process."
WebAlkylation of Ph 3 P=CH 2 with a primary alkyl halide R−CH 2 −X, produces substituted phosphonium salts: Ph 3 P=CH 2 + RCH 2 X → Ph 3 P + CH 2 CH 2 R X − These salts can be deprotonated in the usual way to give Ph 3 P=CH−CH 2 R. Deprotonation Although ylides are "electron-rich", they are susceptible to deprotonation of alkyl substituents.
