| Popis: | Reaction of the –CH2OSiMe3 substituted allyldimesitylphosphane 5 with HB(C6F5)2 resulted in a hydroboration/(C6F5)2BOSiMe3 elimination sequence to give the phosphinomethyl substituted cyclopropane derivative 9, probably via a phosphiranium type intermediate. Addition of B(C6F5)3 to compound 5 gave the stable phosphiranium/borate zwitterion 10 that was isolated and characterized by X-ray diffraction. |
