In this paper we investigate commutator conditions for two strongly continuous semigroups ${(T(t))_{t\geq 0}\,}$ and ${(S(t))_{t\geq 0}\,}$ on a Banach space implying the convergence of the Lie-Trotter products $[T(\tfrac{t}{n})S(\tfrac{t}{n})]^n$ . The results are then applied to various examples and, in particular, to the Ornstein-Uhlenbeck operator.
