We study the semileptonic decays B± → η (′)lv, which are suggested to be used to extract the hadronic form factors of B meson decays to η(η′) and the angle of η- η′ mixing. This would be of great benefit to theoretical studies of B nonleptonic decays involving η and η′, and could lead to a reliable and complementary determination of Vub. The branching ratios are estimated to be Β(B± → η (′)lv) = 4.32±0.83 (2.10±0.40) × 10 -5, which could be extensively studied experimentally at BaBar and Belle.
