Preparations of some tributyltin phosphates

Different complex tributyltin organophosphates have been prepared; in some cases the organotin cation is directly linked to the phosphate group, in other cases it is linked to a carboxylate or to a thioate function in a RO-P substituent. The direct phosphorylation of a tributyltin hydroxy salt is only possible for a marked covalent salt. Intramolecular rearrangements were observed.
