Abstract
Sterically demanding secondary phosphines and phosphides react with (THF)B(C6F5)3 (THF = tetrahydrofuran) to give the THF ring-opened compounds [R2PHC4H8OB(C6F5)3] and [Mes2PC4H8OB(C6F5)3Li(THF)2] (Mes = C6H2Me-2,4,6). These reactions also occur consecutively to give the double THF ring-opened compounds [Mes2P(C4H8OB(C6F5)3)2][Li(THF)4] and [t-Bu2P(C4H8OB(C6F5)3)2Li].Keywords
