A series of classical B(C(6)F(5))(3)-phosphine adducts are shown to be reactive molecules. Reaction of (THF)B(C(6)F(5))(3) with phosphines are shown to effect ring-opening of THF affording the zwitterionic phosphonium-borate species of the form R(2)PH(C(4)H(8)O)B(C(6)F(5))(3) and R(3)P(C(4)H(8)O)B(C(6)F(5))(3). Alternatively, treatment of (THF)B(C(6)F(5))(3) with a lithium phosphide (R(2)PLi, R = tBu
一系列经典的B(C(6)F(5))(3)-膦加合物显示为反应性分子。(THF)B(C(6)F(5))(3)与膦的反应显示出THF的开环作用,从而得到形式为R(2)PH(C(4))的两性离子硼酸phospho盐物种H(8)O)B(C(6)F(5))(3)和R(3)P(C(4)H(8)O)B(C(6)F(5))(3 )。或者,用磷化锂(R(2)PLi,R = tBu,Ph Mes)处理(THF)B(C(6)F(5))(3),得到[Li(THF)( x)] [R(2)P(C(4)H(8)O)B(C(6)F(5))(3)]。此外,双THF开环也被证明可以形成[Li(THF)(x)] [R(2)P(C(4)H(8)OB(C(6)F(5)) )(3))(2)]。此外,还显示了一系列经典的硼烷-膦加合物进行热重排反应,以得到芳香族取代基R(2)PH(C(6(F)4(4))BF(C(6)F(5))的两性离子产物。
