An unprecedented adduct 10 between triphenylphosphine (TPP) and 3,3-dimethyl-1,2,5-thiadiazolidine 1,1-dioxide (8) is described, which can be regarded las a stable source of the [Ph(3)P](+) species, and was utilized to efficiently promote the coupling between alcohols and carboxylic or nitrogen acids in a Mitsunobu-like manner.

This invention provides an improved synthesis of polymer conjugates of formula (I),
of agricultural, therapeutic, and food additive compounds. In particular, a process is described for the preparation of conjugates by treating primary or secondary alcohol substituents of active compounds with polymeric nucleophiles using “Mitsunobu” or related reaction conditions.
