| Abstract: | Abstract New phosphorus- and selenium-containing heterocyclyes, 1,3,2,6-dioxa-phosphaselenacyclooctanes (la-lo), were synthesized in ca. 10% yields from 3-selena-l,5-penta-diol and RP(X)Cl2 where R = alkoxyl, aroxyl, aryl and X = 0 or lone pair. Three macrocycles 3, 4 and 5, which were expected to be heterodinucleating ligands, were obtained in moderate yields (20–30%) from bis(o-bromomethylpheny1)phenylphosphine oxide 2 and corresponding selenium-containing materials. |
