A triester method for the synthesis of deoxynucleoside phosphorodithioate dimers is described. The phosphorodithioate linkage is introduced using a new dithiophosphorylating reagent DPSE-SP(S)Cl(2)where DPSE = 2-diphenylmethylsilylethyl. This group is removed quickly using tetra-butylammonium fluoride leading to the quantitative formation of
