Reactions of diethyl vinyl phosphite and divinyl methyl phosphite with iodine produce exclusively dealkylated intermediates, the highly reactive vinyl and divinyl phosphoroiodidates, which can be used as efficient phosphorylation reagents to prepare a variety of vinyl and divinyl organophosphorus compounds. Examples are given for the ethyl vinyl and divinyl analogs of the potent diethyl phosphate anticholinesterase agents diazoxon, chlorpyrifos oxon and paraoxon.
