This paper reports a simple two step process by which a large variety
of 1,3-bis(dialkylphosphino)propanes can be prepared on an industrial
scale. The first stage is the preparation of an allyldialkylphosphine
which is then followed by free radical addition of a dialkylphosphine
to the allyl functional group to yield the subject compound
