We study the semileptonic decays B^\ifmmode±\else\textpm\fi\ensuremath→\ensuremathη^(\ensuremath')l\ensuremathν, which are suggested to be used to extract the hadronic form factors of B meson decays to \ensuremathη(\ensuremathη^\ensuremath') and the angle of \ensuremathη\ensuremath-\ensuremathη^\ensuremath' mixing. This would be of great benefit to theoretical studies of B nonleptonic decays involving \ensuremathη and \ensuremathη^\ensuremath', and could lead to a reliable and complementary determination of Vub. The branching ratios are estimated to be B(B^\ifmmode±\else\textpm\fi\ensuremath→\ensuremathη^(\ensuremath')l\ensuremathν)=4.32\ifmmode±\else\textpm\fi0.83 (2.10\ifmmode±\else\textpm\fi0.40)\ifmmode×\else\texttimes\fi10^\ensuremath-5, which could be extensively studied experimentally at BaBar and Belle.
