cholesteryl phosphorodichloridate has been examined. Reaction of thiophosphoryl chloride and cholesterol gave cholesteryl thionophosphorodichloridate but this could not be hydrolysed to the phosphate. Treatment of cholesterol with phosphorus pentasulphide gave OO-dichol-esteryl hydrogen phosphorodithioate contrary to previous reports. A study has been made of the decomposition of cholesteryl phosphorodichloridate

The preparation of the following steroid phosphorodichloridates is described: cholestanyl, epicholestanyl, epicholesteryl, and the derivatives of methyl 3α-hydroxy-5β-chlolanate, and ergosta-8(14)en-3β-ol. The formation of the phosphorodichloridates was followed by t.l.c. Attempted phosphorylation of 3,5-cyclocholestan-6β-ol, and 6β-hydroxycholest-4-en-3-ol gave cholesteryl phosphorodichloridate and
