We study the potential effects of anomalous couplings of the third generation quarks to gauge bosons in rare B decays. We focus on the constraints from flavor changing neutral current processes such as \stackrel\ensuremath→bs\ensuremathγ and \stackrel\ensuremath→bsl+l^\ensuremath-. We consider both dimension-four and dimension-five operators and show that the latter can give large deviations from the standard model in the still unobserved dilepton modes, even after the bounds from \stackrel\ensuremath→bs\ensuremathγ and precision electroweak observables are taken into account.
