REACTION OF PHOSPHOLES WITH ACIDS; PROTON SHIFTS IN 1H-λ5-PHOSPHOLES

Addition to phospholes of gaseous HCl at -90 deg C or of an excess of trifluoromethanesulphonic acid at -70 deg C, results in P-protonation.The triflate solutions are stable up to room temperature, but the 1H-phospholium chlorides form PV adducts at -70 deg C, which rapidly rearrange by a sigmatropic H-shift.The observed product is a 1-chloro-2,5-dihydrophospholium chloride.Addition of a chloride ion source to the triflates produces the same result.Unprotonated 3,4-dimethyl-1-phenyl phosphole was found to react at a double bond of its 1H-phospholium ion, forming a crystalline 1,3'-biphospholium dimer.
