N2 - Four phosphorylation procedures were used in the preparation and characterization of sundry steroid phosphate and phosphonate esters, as well as some P1,P2-disteroid pyrophosphates. An attempt to prepare cholest-3,5- dien-3-yl dialkyl phosphate by a vinylogous Perkow reaction from 6- bromocholest-4-en-3-one yielded only dienenones. As a model for P1,P2- disteroid pyrophosphate (and steroid phosphate) behavior in solution, the neutral crystalline complex 2,2'-bipyridine zinc P1,P2-bis(1-n- dodecyl)pyrophosphate was prepared and characterized.
