Preliminary experiments have shown that the alkaline earth metal ions Mgz+ and Ca2+ and, surprisingly, Hg2+ are also precipitated with the organometallic chelating agents [C,H,Co{ PO(OC,H,),} 3]

Rate constants (k) of radical addition reactions between 15 carbon-and sulfur-centered radicals and 15 vinyl-type alkenes were collected from the literature. Three descriptor variables {a polar (Hammett) sigma scale [s(H)] and two radical sigma scales as defined by Creary and co-workers [s Á (C)] an
