Abstract
The goal of this note is to give, at least for a restricted range of indices, a short proof of homogeneous commutator estimates for fractional derivatives of a product, using classical tools. Both and weighted estimates can be proved by the same argument. When the space dimension is 1, we obtain some new estimates in the unexplored range .
