We recover, by using a Kontsevich's deformation of the Baker-Campbell-Hausdorff formula, Rouviere's results on the convolution of invariant distributions, for solvable symmetric spaces and "very symmetric spaces".21 pages, 10 figures (erreurs typographiques corrigees + des rappels sur la quantification de M.
