## Abstract ^13^C NMR chemical shifts and ^13^Cο£Ώ^31^P couplings are reported for triphenyl phosphate and 13 alkyl derivatives. In __ortho__βalkylated materials, it is found that the upfield Ξ³ shielding effect is only operative when the carbon atom, situated Ξ³ to the exocyclic oxygen, bears at least

This paper pre,;ents a novel method for the chemical synthesis of cholest-4-ene-3,6-dione, which is a naturally occurring steroid and a potential intermediate in steroid chemistry. Pyridinium chlorochromate (PCC) in refluxing benzene has been found to be an effective and convenient reagent for the o
