Abstract: It is shown that if the invariant subspace lattice of a reflexive algebra $ \mathcal{A}$, acting on a separable Hilbert space, is both commutative and completely distributive, then the algebra generated by the rank-one operators of $ \mathcal{A}$ is dense in $ \mathcal{A}$ is any of the strong, weak, ultrastrong or ultraweak topologies. Some related density results are also obtained.
