Aliphatic phosphites have a promotor effect in the radical addition in solution of H2S to propylene photoinitiated as well by direct H2S irradiation as by added benzophenone irradiation.For this last reaction, the phosphite used being (CH3O)3P, the solvent polarity has no effect on the reaction.When the solvent used is a poor hydrogen donnor in a radical reaction, such as benzene, there is an induction period in the case of the benzophenone photoinitiated reaction performed in the presence of a phosphite.It increases for a given aliphatic phosphite with the phosphite concentration and varies with the aliphatic phosphites structure.Light intensity has nearly no effect on the development of the last reaction.
