translate English to French: Reaction of the tetracarbonyl species [M(CO)2(µ-mtz)]2 (M = Rh, Ir; mtz = 2-mercaptothiazolinate) with 1 equivalent of the diphosphines (Ph2P(CH2)nPPh2; n = 1 (dppm), 2 (dppe)) yields the compounds [M2(CO)2(µ-L)(µ-mtz)2] (M = Rh, L = dppm (1), dppe (3); M = Ir, L = dppm (2)), which readily undergo oxidative addition of iodine to give [M2I2(CO)2(µ-L)(µ-mtz)2] (M = Rh, L = dppm (4), dppe (6); M = Ir, L = dppm (5)).
La réaction des espèces tétracarbonylées [M(CO)2(µ-mtz)]2 (M = Rh, Ir; mtz = 2-mercaptothiazolinate) avec un équivalent de diphosphines (Ph2P(CH2)aPPh2; n = 1 (dppm), 2 (dppe)) fournit les composés [M(CO)2(µ-L)(µ-mtz)2] (M = Rh, L = dppm (1), dppe (3); M = Ir, L = dppm (2)), qui subissent l'addition oxydative d'iode pour donner les [M2I2(CO)2(µ-L)(µ-mtz)2] (M = RH, L = dppm (4), dppe (6); M = Ir, L = dppm (5)).
